chore(03): close Phase 03 — transition to Phase 04

- 03-08-SUMMARY (Gate 2 record) written; phase marked complete (12/12)
- ROADMAP: Phase 3 [x] complete 2026-06-07; REQUIREMENTS updated
- STATE: advanced to Phase 4, focus + progress corrected (backlog 999.x were
  miscounted as milestone phases → reset total_phases to 5, 60%)
- PROJECT.md evolved: event CRUD / OIDC login / iOS PWA install moved to
  Validated (Phase 3); D-17 logged; Android install + onboarding-provider-setup
  kept Active
- removed stale .continue-here + one-shot HANDOFF.json

Carried forward: B5 (Android install), Phase 4 SSE entry gate (D-14), backlog 999.3-999.9.

-Last session: 2026-06-07 — Completed quick task 260607-l6l (write-path bug batch)
-Stopped at: Edit/delete 503 blocker RESOLVED (missing calendars join), displayName + GET-events-filter fixed. Code on gsd/v1.0-milestone; build clean, 100/100 api tests pass. NEXT: operator must rebuild (docker compose up -d --build) and browser re-test delete/edit + legend name. Remaining Gate 2 items (A2/A3 session+2nd-member-color, B iOS install, C SSE smoke) are human/device checkpoints — see HANDOFF.json.
