chore(meta): docs/build sweep + tooling test gate (T-1069, T-1066)

- make test-tooling: planet-gen determinism guard + import_economics
  --dry-run, wired into pre-push on TOOLING_CHANGED; ruff widened to
  E4/E7/E9/F/W (90 safe auto-fixes applied; E402/E702/F841 ignored with
  documented counts)
- one-generator reality fixed in DEVOPS.md, asset-pipeline rule, CLAUDE.md
  (import_economics sole generator since #951/D-223); dead check-protocol
  target deleted; DEVOPS hook/config sections rewritten from the actual
  hook sources; team-patterns gate description updated (client+tooling)
- project.yaml: 0.2.0 → 0.4.0 per the 0.{phase}.{n} scheme, description
  refreshed from the v0.1 Sova narration to cascade reality
- stale comment sweep: voxel.rs stub claims (all 8 families implemented),
  cascade.rs TODO recited to T-1044, main.rs D-192 handshake claim,
  relationships.rs/chunk_streaming.rs version targets → phase language
- gitignore: client/settings.db* e2e-run artifacts
