docs(phase-04): closure ceremony — milestone v1 complete

phase.complete CLI ran (commit n/a — CLI in-mem only) with documented
defects per recurring state.record-session bug:
- completed_phases stuck at 3 (should be 4)
- percent regressed to 75% (3/4 math; should be 100% — milestone-complete)
- ROADMAP Phase 4 row still [ ] despite roadmap_updated:true claim

Manual fix applied per saved memory (canonical workaround for CLI bug):

STATE.md:
- completed_phases: 3 → 4
- percent: 75 → 100
- progress bar: [█████████▓] 97% → [██████████] 100%

ROADMAP.md:
- Phase 4 row: [ ] → [x] with comprehensive closure annotation
  (8 plans + 3 debug sessions + 4 ROADMAP SCs + 5 D-P4-* + UAT
  33→36 + vitest 171→188 + bundle gates 6/6 + Tier-1 12 + Tier-2 added
  + operator ack 2026-05-26 + verifier audit PASSED 8ffc6cb)

Phase 4 closed end-to-end. Milestone v1 v2.0.0 complete (status:
milestone_complete already correctly set by CLI). Ready for v1.0 tag +
alpha redistribution per D-P4-04 (user routes out-of-band).
