feat(ts): add real quality gates — Biome lint + effect-law ratchet + class inventory

- biome.json (2.4.16, linter-only) wired as "lint" in all six packages
- scripts/check-effect-laws.ts: Effect-native law enforcement encoding the
  adapted beep-effect effect-first/schema-first laws (no native JSON/switch/
  sort/fetch/timers, no process.env, no throw new, no Effect.run* outside
  boundaries, no Schema-suffixed constants, no node:fs/path, AST-based
  pure-data interface detection per law 38/39)
- ratcheting baseline allowlist (95 entries / 290 findings) that must shrink
  to documented exemptions only; stale counts fail the gate
- root lint chains turbo lint + law check + native-class inventory
- fix all 163 initial Biome findings: import-type style, templates, two `any`s,
  ten non-null assertions (librarian getService gate, A.matchRight in atoms,
  ensureNode returning nodes, main.tsx mount guard)

Gates: lint, check:tsgo, build, test (force, 11 tasks) all green.
