release: v2.2.1 — Windows embeddings fix + backfill safety + first-run guide (#105)

* patch(backfill-safety): VESTIGE_BACKFILL_AUTOFIRE gate (default OFF) + bounded promote_memory_backfill

Off-by-default env gate around step-8.5 auto-fire in run_consolidation (decouples
backfill from consolidation cadence). New promote_memory_backfill caps stability at
MIN(stability*1.5, stability+365.0) (the bound retroactive_backfill.rs:300 already
computes but discarded); both backfill entry points use it. Fixes the false 'capped'
comment. Cloud-sync excluded at build (--no-default-features). Pending upstream PR to
samvallad33/vestige. omega-backfill-safety-v2.2.0 off tag v2.2.0 (3bcd4667).

* release: v2.2.1 — Windows embeddings fix + backfill safety + first-run guide

Board-clearing patch release.

Fixes:
- #101 Windows embeddings: release.yml already restores vector-search on the
  x86_64-pc-windows-msvc target (merged in #102); this release rebuilds the
  Windows binary so users actually get working embeddings.
- #103 Retroactive Salience Backfill safety (from community PR #104, adjusted):
  * promote_memory_backfill bounds the stability multiply to
    MIN(stability*1.5, stability+365.0) on both auto-fire and manual paths.
  * VESTIGE_BACKFILL_AUTOFIRE gate — default ON (preserves the shipped/documented
    v2.2.0 behavior), disable with 0/false/off/no. Env value is trimmed.
  * Corrected the false "capped" comment and the promote_memory_backfill doc.
  * Added 3 tests: +365 cap binds, *1.5 multiply below crossover, gate parsing.

Docs:
- #83 First-Run: new docs/GETTING-STARTED.md + README pointer.
- Consolidated roadmap issues #82,#84-#92 into docs/ROADMAP.md (Tracked Issues).
- Documented VESTIGE_BACKFILL_AUTOFIRE in docs/CONFIGURATION.md.
- CHANGELOG v2.2.1 entry.

Version bumped to 2.2.1 across all manifests + Cargo.lock + dashboard build.
