chore(deno): migrate toolchain from Node 24 + pnpm to Deno 2.9.7 + TypeScript 7.0.2 (W1.5)

- root deno.json workspace (nodeModulesDir auto), npm versions registered once in imports, deno.lock;
  remove pnpm-lock/pnpm-workspace/root package.json; members keep minimal package.json (name/type/exports)
- tasks: dev, typecheck (tsc 7.0.2 per member + deno check), lint/fmt (biome, useImportExtensions),
  test (vitest via deno), check:tokens, build (web + deno compile), ci, db:migrate/reset, gen:types
- tsconfig base moved to config/ (no root tsconfig.json); deno types -> types/deno.d.ts; web drops baseUrl
- server: Deno.serve entry with graceful shutdown, --role migrate|preflight|probe, WEB_ROOT static SPA hosting;
  drop @hono/node-server, tsx, esbuild build.mjs
- logger: redact child() bindings and serialize err by message/stack; sync stdout destination; tests
- relative imports get explicit extensions (sites/mp-sync paths left for follow-up)
- crash-recovery tests spawn `deno run -A`; tasks tests use unique per-file schemas
- single-container Dockerfile + entrypoint (migrate -> preflight -> api+worker watchdog), docker-compose.yml
- docs: README, runbook, ADR-001 superseded, plan §1 validation row
