docs: add gap-closure phases 42-44 for UAT audit findings

[FSM1]

Summary

Inserts three gap-closure phases into milestone v1.1 covering the five high-severity todos captured from the 2026-06-11 UAT audit, grouped by coupling:

Phase	Name	Covers
42	api-unpin-integrity	unpin ownership check + cross-user CID refcount + pinned_cids row delete + quota decrement (todos: ipfs-unpin-missing-ownership-check, server-quota-never-decremented-on-unpin)
43	fuse-write-durability	persisted pending-upload journal + mkdir parent-publish retry, macOS + Windows (todos: fuse-release-data-loss-before-remote-commit, fuse-mkdir-parent-publish-orphan)
44	ipns-conflict-handling	merge-on-409 for folder metadata + CAS for file records; full CRDT model deferred (todo: ipns-409-retry-lost-update)

All three depend only on Phase 41 and can proceed independently — ordered by urgency (42 closes a live cross-tenant deletion hole) and ascending design risk.

Changes

• ROADMAP.md: three phase entries with goals + todo references; corrected auto-generated dependency chain (42→43→44) to independent deps on Phase 41
• STATE.md: Roadmap Evolution entries, status "Milestone complete" → "In progress — gap closure", counters 26 → 29 phases
• Phase directories with .gitkeep

Source todos remain in .planning/todos/pending/ until consumed by discuss/plan.

Changes

Gap Closure Phases 42–44

Layer / File(s)	Summary
Roadmap phase definitions .planning/ROADMAP.md	Phase 42 addresses API unpin integrity with ownership verification and quota consistency checks; Phase 43 adds FUSE write durability via pending-upload journal and mkdir orphan fix; Phase 44 handles IPNS conflict resolution with 409 retry behavior and CAS coverage. Footer metadata updated with new last-updated date and gap closure accounting.
Project state and progress tracking .planning/STATE.md	Milestone status changed to "In progress — gap closure (phases 42-44)", last-updated timestamp advanced to 2026-06-12, progress totals raised from 26 to 29 phases, current focus set to "Gap closure — UAT audit findings", and phase descriptions added for phases 42–44 with audit-gap-closure scope.
Phase directory placeholders .planning/phases/42-api-unpin-integrity/.gitkeep, .planning/phases/43-fuse-write-durability/.gitkeep, .planning/phases/44-ipns-conflict-handling/.gitkeep	.gitkeep files establish version control directories for the three new phases.
