Long expeditions D7-c: -days flag + per-day snapshots in SimResult

cmd/expedition-sim -days N caps runs by synthetic day rollovers
(Outcome="day_capped"). SimResult.DaySnapshots traces HP/SU/threat/rooms
at start, every Night-camp rollover, and end-of-run — unblocks empirical
D5-d retune of phase5BDailyBurnRatePct against per-day SU draws.

**D7-b (shipped 2026-05-27):** `SimRunner.RunExpedition` now drives the production camp scheduler under a synthetic clock (`simWalkInterval = autoRunCooldown`, 2h per walk). After every soft-stop walk it calls `maybeAutoCamp(exp, simNow)`; `stopBossSafety` routes to `pitchBossSafetyCamp(exp, simNow)`. The helpers (`applyAutoCamp` / `applyAutoCampBossSafety`) advance `simNow` past `minAutoCampDwell` (4h) and break the auto-pitched camp via `breakAutoCampIfDue` so the next walk proceeds. `maybeAutoCamp`, `pitchAutopilotCamp`, and `pitchBossSafetyCamp` gained a `now time.Time` parameter (the only prod caller, `tryAutoRun`, still passes `time.Now().UTC()`). Effect: HP-low mid-day rests, multi-region base-camp waypoints, Night-camp rollovers, and boss-safety holds all fire under the sim — the D7-a `tickEventAnchoredRollover` shortcut is no longer used by RunExpedition (kept on TickDay for tests + the pre-cutoff legacy path). Coverage in `expedition_sim_test.go`: Night-camp day advance, HP-low mid-day rest, boss-safety force-pitch, no-op when neither trigger fires.
**Remaining work (D7-c+):**
- `cmd/expedition-sim` extensions: multi-day mode CLI flag (`-days` / per-day SU/HP/threat snapshots in SimResult).
**D7-c (shipped 2026-05-27):** `cmd/expedition-sim` gained a `-days N` flag — when set, `RunExpedition` exits with `Outcome="day_capped"` after the Nth synthetic day rollover; 0 (default) is unbounded and only the existing `-cap` walk safety net applies. `SimResult` gained `DaySnapshots []SimDaySnapshot` ({Day, HPCurrent, HPMax, Supplies, Threat, Rooms}), captured at expedition start (Day 0), after every `applyAutoCamp`/`applyAutoCampBossSafety` Night-camp rollover, and one final end-of-run entry (reads `getExpedition(mostRecentExpeditionID(...))` when the row already extracted so closed runs still close their trajectory). `RunExpedition` signature picked up the `maxDays int` parameter; sole caller is the CLI. Coverage: `TestSimRunner_CaptureDaySnapshot_PopulatesFields` exercises the helper in isolation (HP from the live character row, SU/threat/day from the live expedition, Rooms from `res.Rooms`). Unblocks empirical D5-d retune of `phase5BDailyBurnRatePct` against per-day SU draws.
**Remaining work (D7-d+):**
- Re-run the class win-rate corpus (cross-link `project_class_balance`, `project_j2_sim_artifact`).
- Re-check trailers (bard/cleric per `project_j1_post_sweep_findings`) — autopilot camp pacing may relieve their HP-cliff issue.
- D5-d retune of `DailyBurn` / `phase5BDailyBurnRatePct` against measured day-counts.
