Fusion 78b5a1b7ae feat(FN-2849): merge fusion/fn-2849-2

- **Node routing & diff visibility** (FN-2840, FN-2910): Strengthened node routing with improved task diff visibility; `resolve-diff-base.ts` now prefers `merge-base` over potentially stale `baseCommitSha`; added `unavailable-node-policy` and `node-override-guard` tests
- **Concurrency races fixed**: Executor and merger now synchronize worktree lifecycle more defensively; reviewer pause/unpause fixed against TOCTOU races in `concurrency.ts`
- **Richer merge commit messages**: `merger.ts` and `ai-summarize.ts` enhanced to generate AI-summarized merge messages via the summarizer pipeline
- **Memory dream improvements**: `memory-dreams.ts` reads assistant text from session state when processing dreams; added coverage for undefined output edge cases
- **QuickChatFAB UI**: New floating action button component with chat integration (226 lines TSX, 140 lines CSS); `useQuickChat.ts` refactored for better state management; tests added
- **Task changes display**: `ChangesDiffModal` and `TaskChangesTab` now surface only files actually modified by the task, not the full diff baseline
- **Self-healing hooks**: `self-healing.ts` extended with additional recovery logic for agent runtime
- **Documentation**: Added `docs/multi-project.md` (central registry, isolation modes), `docs/architecture.md` (node settings sync API), `docs/task-management.md` (archive/restore), `docs/cli-reference.md`; updated `docs/settings-reference.md`
- **Gitignore**: Allow committed `.changeset/` directories
- Merged in FN-2734 and FN-2957 as part of this branch
