Sunday email nudge, touched dreams, deeper questions, turn history

[sarthakagrawal927]

Summary

Closes the four gaps between the weekly log and "a life you want to live":

• Sunday pull (opt-in): a users.weeklyEmailOptIn toggle on the log flips on a quiet Sunday email — Cloudflare Email Sending (EMAIL binding) fired by a cron (0 22 * * 6 + 0 14 * * *). The handler emails only owners whose local day is Sunday and whose current week has no entry — a written week is never nudged. Copy is no-streak, no-guilt by contract.
• Reconciliation: detectDreamTouches matches entry prose to dream titles/categories on-device-read-only; the log now shows "This week touched" chips and removes touched dreams from "Still calling?". No fake state written.
• Question depth: bank 30→50 (5/family); when a classifier-picked family is exhausted, Workers AI generates a question from the same categorical context — prose still never leaves the app.
• Turns persist: interview Q&A stored on WeeklyLogEntry.turnsJson (+ local record), so Weeks on record renders the prompts alongside answers.
• Migration 0006 (additive: weeklyEmailOptIn, turnsJson) — apply remote before deploy.

Test plan

• pnpm quality — all gates green
• Unit: sender (Sunday filter, skip-written, opt-in, failure resilience), detectDreamTouches, turn-aware context
• E2E: interview flow, persistence, axe — green in both modes
• wrangler deploy --dry-run — env.EMAIL (unrestricted) Send Email binding resolves
• Cron handler smoke-fired locally via --test-scheduled
• pnpm db:migrate:remote for 0006
• Post-merge deploy via workflow
