fix(npm): implement ADR-263/264/265 — harness fail-closed + async MCP, rvagent packaging/transport/naming, npm CI+provenance gate

ADR-263 (@ruvnet/ruview 0.2.0), O1-O9:
- claim-check fails closed on empty input (CLI exit 2, empty_text tool error)
- MCP stdio server dispatches tools/call asynchronously (promise-based spawn);
  ping answers while a 3s fake verify runs — pinned by new e2e test
- optionalDependencies dropped: cold npx installs exactly 1 package
  (MEASURED: was 4 pkgs/620kB/71 files via npm i in a clean prefix)
- bounded rolling output tails replace spawnSync 1MiB maxBuffer
- node_monitor port passed via sys.argv, never spliced into python -c source
- serverInfo.version read from package.json; resources/prompts stubs
- skills single-sourced: prepack sync script generates .claude/skills/ copies
- which() = memoized dep-free PATH scan
- tools underscore-canonical (ruview_claim_check, ...) + dotted aliases
- guardrail precision: word-boundary map/f1/auc/iou, code-span + F1/O2 label
  scrubbing, quantitative-claims-only; packaging reproducer hints
- 30/30 tests (was 17), incl. concurrency e2e + fail-open regression pins

ADR-264 (@ruvnet/rvagent 0.2.0), O1-O9:
- exports fixed: types-first, phantom dist/index.cjs require target removed
- tarball map-free: 127,704B unpacked / 46 files / 0 maps (MEASURED,
  npm pack --dry-run; was 188kB incl. 44 maps referencing unshipped src)
- Streamable HTTP actually wired behind RVAGENT_HTTP_PORT: one transport +
  one MCP server per session (mcp-session-id routing), 1MiB body cap (413),
  port-aware localhost origin gate; dual-transport description now true
- tools renamed underscore-canonical with dotted router-only aliases
- single Zod validation gate; advertised inputSchema generated from the same
  Zod source (zod-to-json-schema)
- train_count: parent log fds closed (was leaking 2/job); job records
  persisted to <jobsDir>/<id>.json (job_status survives restarts); bounded
  log-tail reads
- detectCogBinary probes its candidates instead of dead-coding them
- version from package.json; @types/express dropped; @types/jest -> 29
- README rewritten to match reality (no phantom subcommands/policy layer)
- 99/99 jest tests (incl. new session/body-cap suite + previously-broken
  manifest suite); stdio handshake + HTTP session flow smoke-tested live

ADR-265 D1-D4:
- .github/workflows/npm-packages.yml: 3-package x Node 20/22 gate — tests,
  version-literal grep (D3), pack-content/size gate, tarball-install smoke
  test (catches the ADR-264 F1 class), README claim-check (D4)
- .github/workflows/ruview-npm-release.yml: publish from CI only with
  npm publish --provenance
- @ruv/ruview-cli bin renamed ruview-cli (ruview bin belongs to
  @ruvnet/ruview); version single-sourced
- ci.yml NODE_VERSION 18 -> 20

ADR statuses updated to Accepted/implemented; harness manifest re-pinned;
ADR-263/264/265 + both package READMEs pass claim-check.

+# Manual `npm publish` from laptops stops: this workflow re-runs the ADR-265 D1
+# gate for the selected package and then publishes with npm provenance
+# attestations (OIDC), tying every published version to a public commit +
+# workflow run — the npm-side analogue of the ADR-028 witness bundle.

+# Requires: NPM_TOKEN repo secret (an npm automation token), or npm Trusted
+# Publishing configured for the package (in which case the token is unused).
