chore(release): v2.2.0 — Retroactive Salience + Tool Consolidation

Version bump 2.1.27 -> 2.2.0 across workspace crates + npm packages.

v2.2.0 = three coherent value streams:
- Retroactive Salience Backfill (Cai 2024 Nature) — memory with hindsight
- MCP Tool Consolidation (34 -> 13 advertised tools)
- deep_reference engine upgrades (F32 / RRF / claim-contradiction / band-gate)
  + recall/compose CLI
- security & correctness audit-swarm fixes

The Black Box / trace-receipt / cloud-sync / launch-UI bundle (PR #98) is a
separate coupled feature stream and ships as its own follow-up release.

Gates: 1550 tests pass, clippy -D warnings clean, dashboard check + build clean.
