Editor: Find & Replace, read-aloud, backup, typography, phonetic, org niceties

Writer power-ups (Phase 11), plus the selection-bubble vs copy/paste fix.

- Find & Replace (Ctrl/Cmd+F): SearchHighlight decoration extension +
  FindReplace bar (match-case, replace-all back-to-front, scroll without
  popping the selection bubble).
- Read-aloud (Web Speech, offline) on the word card and selection bubble.
- Keyboard/touch access to the ESL helpers: Ctrl/Cmd+D look up word at caret,
  Ctrl/Cmd+J rewrite selection, touch long-press lookup. Refactored the
  right-click handler into a shared openWordLookup(pos).
- Whole-corpus backup: GET /api/docs/export-all zips every doc (md/docx),
  de-dupes filenames, dated name; sidebar download links. TestExportAll.
- Smart typography input rules (curly quotes/em-dash/ellipsis), ASCII-only so
  CJK is untouched.
- Duplicate doc, sidebar sort (Recent/Title/Longest), toolbar outline popover.
- English phonetic (chosen over pinyin for an English learner): ECDICT-built
  phonetic.json.gz (46,579 words) + Result.Phonetic + WordCard IPA line;
  scripts/build_phonetic.py (full build + --seed fallback).
- Selection bubble no longer blocks copy/paste: deferred to pointer-up and made
  click-through except on its buttons.

 - Tests: `tags_test.go` (full lifecycle — create/idempotent/color-coerce/rename-recolor/assign/unassign/doc-list inclusion/roster counts/delete-cascade/404s), `search_test.go` (EN FTS, CJK FTS, 2-char CJK LIKE fallback, title-only, case-insensitive, empty/no-match, **edit re-indexes via the update trigger**). go build/vet/test clean, tsc clean, vite build OK. Live smoke vs the binary on a throwaway DB (port 8061, LLM pointed at a dead host): search EN/CJK/2-char all highlighted, tag create+assign+roster-counts+doc-list-tags+delete-cascade, check→502 (warm path), new CSS classes (`petal-tag-chip`/`petal-scrim`/`petal-drawer-open`/`pointer:coarse`) and the 小助手在休息 string present in the served bundle. FTS backfill of pre-existing docs verified separately.
 - **Known limitations**: trigram FTS snippets/ranking treat the query as a contiguous phrase (multi-term relevance is substring, not BM25-per-term) — fine for a personal corpus. Search is title+body only (not tag names). Hover gloss and right-click word lookup remain pointer-oriented (long-press contextmenu on touch is browser-dependent); the spelling/suggestion cards and rewrite bubble are fully touch-reachable.
 
+### Phase 11 — Writer power-ups ✅
+- [x] **In-document Find & Replace (Ctrl/Cmd+F)** — `SearchHighlight` ProseMirror extension (decorations, not marks — same anchoring discipline as the suggestion/spell layers; matches recomputed per-textblock on every edit, never stranded). `FindReplace` bar (bilingual zh-first): live match highlighting, ↑/↓ step-through with no-selection DOM scroll-into-view (so it never pops the rewrite bubble), match-case toggle, replace / replace-all (replace-all applies back-to-front so earlier edits don't shift later positions). Honey wash on all matches, rose ring on the active one.
+- [x] **Read-aloud / TTS** (`web/src/audio/speech.ts`) — Web Speech API, offline, feature-detected. 🔊 in the `WordCard` (pronounce the word) and the selection bubble (read the selection). Pairs with the phonetic line.
+- [x] **Keyboard + touch access to the ESL helpers** — refactored the right-click word-lookup into a position-based `openWordLookup(pos)`; now also driven by **Ctrl/Cmd+D** (look up the word at the caret) and a **touch long-press** (~500ms, the touch equivalent of right-click). **Ctrl/Cmd+J** rewrites the selection more naturally. (Closes the "pointer-only" limitation noted in Phase 10.)
+- [x] **Whole-corpus backup** — `GET /api/docs/export-all?format=md|docx|…` zips every doc (reuses the per-doc renderers; de-duplicates same-titled filenames; dated `petal-backup-YYYY-MM-DD.zip`). Static route takes priority over `/{id}` in chi — covered by `TestExportAll`. Sidebar footer "备份 · Back up all: Word / Markdown" download links.
+- [x] **Smart typography** (`Typography.ts`) — dependency-free input rules: curly quotes, em-dash (`--`), ellipsis (`...`). ASCII-only triggers so CJK fullwidth punctuation is untouched; every rule is plain-Undo-able.
+- [x] **Org niceties** — duplicate-a-document (App `handleDuplicate` → "… (副本)", copies body/tone, not tags), sidebar **sort** (Recent / Title / Longest), and a **document outline** popover in the toolbar (headings → click to scroll, indented by level).
+- [x] **English phonetic (pivot from pinyin)** — for a native-Mandarin English learner the useful pronunciation aid is the English IPA, not pinyin (she reads Chinese fluently). `scripts/build_phonetic.py` extracts ECDICT's `phonetic` column (same source/freq-gate as the gloss); `phonetic.json.gz` embedded + lazily loaded; `Result.Phonetic` resolved via the same de-inflecting candidate walk; shown as `/ˈrɪvər/` in the WordCard. **Full dataset built from ECDICT: 46,579 words (361KB gz)**, in line with the other lexicon assets. The script also has a `--seed` mode (71 curated common words) that ships as a fallback / works without the csv. Curated seed entries (clean IPA) override the ECDICT form where both exist.
+- Verified: go build/vet/test (incl. new `TestExportAll`), tsc, vite build all clean; live smoke vs throwaway binaries — `/word/river|running|serendipity|rivers` all return phonetic (`rivers`→`river` de-inflected), export-all returns a valid 2-entry zip with de-duped CJK filenames + dated name, route doesn't collide with `/{id}`.

 ## Session log
+- 2026-06-26: **Phase 11 complete** (writer power-ups, batch requested as "do it all"). Seven features: (1) in-doc **Find & Replace** — `SearchHighlight` decoration extension + `FindReplace` bar (Ctrl/Cmd+F, match-case, replace-all back-to-front, DOM scroll that doesn't trigger the selection bubble); (2) **read-aloud** Web Speech util + 🔊 in WordCard & selection bubble; (3) **keyboard/touch access** — Ctrl/Cmd+D caret lookup, Ctrl/Cmd+J rewrite, touch long-press (refactored `handleContextMenu` → shared `openWordLookup(pos)`); (4) **export-all** backup zip (`GET /api/docs/export-all`, `TestExportAll`, sidebar download links); (5) **smart typography** input-rules extension (curly quotes/em-dash/ellipsis, ASCII-only so CJK untouched); (6) **duplicate doc + sidebar sort + outline popover**; (7) **English phonetic** (pivoted from pinyin — IPA is what an English learner needs; pinyin annotates Chinese she already reads) via `scripts/build_phonetic.py` + embedded `phonetic.json.gz` + `Result.Phonetic` + WordCard `/ˈrɪvər/` line — **full 46,579-word dataset built from ECDICT** (the csv re-download worked; `--seed` mode kept as a csv-free fallback). Also folded in this session: the **selection-bubble vs copy/paste fix** (bubble deferred to pointer-up + container `pointer-events:none` so it never sits where you click). go build/vet/test + tsc + vite all clean; live smoke verified word-phonetic (incl. de-inflection) + export-all zip (de-duped CJK names, route priority). Next: deferred bucket (auth/Copyleaks/deploy), still on hold per user.
 - 2026-06-26: **Phase 10 complete** (organization & polish). Scope confirmed with user: all four areas, **tags** (not folders), **FTS5** search. Backend: migration `0004_tags_and_search` (tags + document_tags + `documents_fts` trigram virtual table with sync triggers + back-fill); `db.Tag` model + color constants; `internal/docs/tags.go` (tag CRUD + idempotent assignment + `tagsByDoc` helper, doc list now carries tags); `internal/docs/search.go` (`GET /api/search`, FTS for ≥3 runes + LIKE fallback for 1-2, Go-built sentinel-highlighted rune-aware snippets, owner-scoped). Mounted `/api/tags` + `/api/search` in main.go. Frontend: `useTags`, `TagChip`/`TagPicker`/`SearchBox`, rewritten `DocList`/`DocListItem` (chips + filter bar + search), `api.search`/tag methods + `splitSnippet`/`tagColorVar`; responsive sidebar drawer (hamburger + scrim, <768px) + `pointer:coarse` tap-target/affordance CSS; tap-to-open + outside-pointerdown-close for suggestion cards (touch); `useCheckpoint` `llmDown` flag → warm bilingual "小助手在休息" StatusBar note. Tests: `tags_test.go`, `search_test.go` (incl. update-trigger re-index). All builds/tests/vet/tsc/vite clean; live smoke vs binary on :8061 (dead LLM host) verified search EN/CJK/2-char, full tag lifecycle, check→502 warm path, bundle contents; FTS backfill of pre-existing docs verified. **All v1 phases (0–7) + post-v1 product (8–10) done.** Remaining: deferred bucket (auth/Copyleaks/deploy), on hold per user.
 - 2026-06-26: **Phase 9 complete** (ESL superpowers: inline Chinese gloss + tone-rewrite). Decisions confirmed with user: gloss is an **offline EC dictionary** (instant, LLM-down-proof, fits the embedded-lexicon ethos), rewrite is a **selection bubble**. Data: `scripts/build_gloss.py` builds `internal/lexicon/data/gloss.json.gz` from ECDICT (66MB csv → 1.3MB gz, 57k freq-≤50k words, cleaned/trimmed). Backend: `lexicon` gloss map + `Gloss()`/`Result.Gloss` + `GET /api/gloss/{word}`; `llm.RunRewrite` + rewrite prompt/`styleGuidance`; `internal/suggestions/rewrite.go` (`POST /api/docs/:id/rewrite`, stateless, owner-scoped). Frontend: `GlossTip` hover tooltip (350ms delay, reuses `wordAt`, CJK-safe) + gloss line in `WordCard`; `SelectionBubble` + `RewritePreview` wired through `EditorCore` (onMouseMove/onSelectionUpdate, request-token guards, clears on edit/doc-switch); `api.glossWord`/`api.rewriteSelection`; CSS for the three new surfaces (+ print-hidden). Tests added in `lexicon` and `suggestions`. All builds/tests/vet/tsc/vite clean; live smoke vs fake vLLM on :8055 verified gloss + rewrite + 400/404/502 paths. Next: **Phase 10 (organization & polish).**
 - 2026-06-26: **Phase 8 complete** (Trust foundation: version history + export) + empty-doc fix. Backend: migration `0003_document_versions`; `internal/docs/versions.go` (throttled auto-snapshot wired into `update`, manual snapshot, restore-with-pre_restore, prune to 40 auto, owner-scoped via join) and `internal/docs/export.go` (pure-Go Tiptap-JSON → md/html/txt/docx, no deps, CJK-safe filenames via RFC 5987). `DocumentVersion` model + kind constants. Tests: `versions_test.go`, `export_test.go` (incl. valid-zip docx assertion). Frontend: `api.client` version/export methods; `ExportMenu` + `HistoryPanel` components wired into the title row; `@media print` stylesheet + `.petal-no-print` for the browser PDF path; `editorEpoch` remount on restore. Empty-doc fix in `App.tsx` (blank drafts reuse-on-create + discard-on-leave via refs to dodge stale closures); deleted 2 orphan empties from the live :8099 DB. Multi-session plan agreed: this session = Phase 8; **Phase 9 (ESL gloss + tone-rewrite)** next, then **Phase 10 (search/folders/polish)**; **auth/deploy (was Phase 11) shelved** until user's foundational work lands. All builds/tests/vet clean; live smoke verified the full version+export+restore flow end-to-end. Next: **Phase 9.**
