feat(post-audit): Phase 4 polish + Phase 2 wiring + Phase 6 cron + CLAUDE.md

Three of the master plan's "suggested execution order" items shipped this
session; Phase 3b (EOI dialog overrides) deferred — estimate exceeded the
remaining session time.

- Phase 4 polish: yachtId field on <ReminderForm> via the existing
  YachtPicker, Ship-icon subtitle on <ReminderCard>, listReminders filter
  by yachtId, getReminder joins the yacht relation.
- Phase 2 risk-signal data wiring: getInterestById derives the 3 dates
  (dateDocumentDeclined / dateReservationCancelled / dateBerthSoldToOther)
  from document_events / berth_reservations / cross-interest interest_berths
  in parallel — chosen over new schema columns to keep the master plan's
  "no new tables" promise. Threaded through to DealPulseChip.
- Phase 6 cron + UI: src/jobs/processors/imap-bounce-poller.ts polls the
  configured IMAP mailbox (IMAP_* env), matches NDRs to recent
  document_sends rows via recipient + 7-day window, idempotent via
  bounceDetectedAt, fires email_bounced notifications on hard/soft
  (skips OOO). State persisted to system_settings.bounce_poller_state.
  Wired into maintenance queue at */15 * * * *. Admin /admin/sends page
  surfaces the bounce badge + reason inline.
- CLAUDE.md: trimmed 27KB → ~19.5KB (~28% smaller bytes). Prose-heavy
  Documenso webhook / v1-v2 routing / Document folders sections rewritten
  as scannable bullets. Added a new "Working in this repo — skills, MCPs,
  agents" section promoting brainstorming/TDD/debugging/frontend-design
  skills, Context7/Playwright/Serena MCPs, and the Explore/feature-dev
  agents. Documented Phase 2 derivation choice in the data-model section.

Quality gates: 1374/1374 vitest pass, tsc --noEmit clean, lint 0 errors.
