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.
