chore(release): v1.16.0

[RudneyForti]

Summary

Release bump for v1.16.0 (MINOR). Closes the batch that has been accumulating in the "Em aberto" group since v1.15.4 — 12 commits, six CS cards, no breaking change.

What ships

CS	Delivery
CS-76	Roadmap rebuilt as a dual-source board: planning lives in PostgreSQL (editable, no commits), git-owned state read live from GitHub, new Revisão column projected from open PRs, server-side write lock, origin tags, PR links, offline fallback
CS-74	"Em aberto" group at the top of Concluídas (merged but unreleased)
CS-73	roadmap-sync.yml — cards move to Concluídas automatically on merge
CS-72	Assisted (read-only) mode with explicit unlock confirmation
CS-71	Label filter on the board
CS-49	Expired session redirects to /login instead of an error screen

Also: repository transferred to the limiarcore organization (repo slug now resolved from a single constant).

E7 checklist

• 1. Version decided via VERSIONING.md + SemVer → MINOR (new user-facing capability, no breaking change)
• 2. package.json bumped → 1.16.0 (lockfile was stale at 1.14.1; synced)
• 3. README.md — badge + footer
• 4. VERSIONING.md — history row
• 5. DOCUMENTATION.md — header, RoadmapCard in the schema map, board.ts description, delivered-features note
• 6. docs/FEATURES.md — Roadmap tab rewritten in non-technical language; CS-49 documented
• 7. docs/QA-TEST-PLAN.md — new §24.2 (RM-01→07) and §24.3 (SE-01), plus KB-08
• 8. docs/DOC-INDEX.md — version stamps
• 9. Merge this PR → tag v1.16.0 → push the tag (deploys automatically)

⚠️ This release changes the schema

Tagging triggers the deploy, and the migrate service will create the RoadmapCard table on production. Production's local layer starts empty by design — planning lives in the 3000 database — so the 4000 board will show Concluídas/Revisão normally with an empty Backlog. Expected, not a failure.
