chore: complete v1.0 Consolidation milestone

Archive milestone artifacts:
- milestones/v1.0-ROADMAP.md (full roadmap archive)
- milestones/v1.0-REQUIREMENTS.md (26/26 requirements complete)
- milestones/v1.0-phases/ (8 phase directories with plans, summaries, verifications)

Updated:
- PROJECT.md: full evolution review, all consolidation requirements validated
- ROADMAP.md: collapsed to milestone summary with archive link
- STATE.md: reset for next milestone
- MILESTONES.md: created with stats and accomplishments
- RETROSPECTIVE.md: created with lessons learned

Deleted:
- REQUIREMENTS.md (archived, fresh for next milestone)

8 phases, 17 plans, 34 tasks, 84 tests added, 6 days

+# Phase 06 Plan 02: Event Codegen Summary
+
+**Go→TypeScript event constant generator using go/ast, fixing LibraryConfigChanged gap and wiring pre-commit drift detection**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-03-05T00:20:57Z
+- **Completed:** 2026-03-05T00:23:43Z
+- **Tasks:** 2
+- **Files modified:** 3
+
+## Accomplishments
+- Built `genevents` codegen tool parsing Go AST for deterministic TypeScript output
+- Fixed missing `LibraryConfigChanged` constant — now automatically generated from Go source
+- Verified codegen-check pre-commit hook detects drift when Go constants change without regenerating TS
+- All 21 event constants synced between Go and TypeScript, frontend typecheck passes
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Create event codegen tool** - `3e9edd0` (feat)
+2. **Task 2: Wire codegen-check pre-commit hook** - No changes needed (lefthook.yml already correctly configured; task was verification-only)
+
+## Files Created/Modified
+- `backend/events/cmd/genevents/main.go` - Go→TypeScript event constant generator using go/ast
+- `backend/events/events.go` - Added `//go:generate` directive for automatic codegen
+- `frontend/src/events.ts` - Regenerated with all 21 constants including LibraryConfigChanged
+
+## Decisions Made
+- Iterated `f.Decls` directly (not collected into map) for deterministic declaration-order output
+- Stripped trailing periods from Go doc comments for cleaner TypeScript comments
+- Used atomic writes (temp file + `os.Rename`) to prevent partial output on failure
+- No lefthook.yml changes needed — existing `codegen-check` hook already runs `go generate ./...` which now includes the event generator
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+None
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Event codegen complete, ready for remaining Phase 6 plans
+- Pre-commit hook validates all generated code (templ, sqlc, events) in <2 seconds
+
+## Self-Check: PASSED
