feat: complete 20-track kernel roadmap (P2P ops, POSIX, HRPC, CI, docs)

- Add optional Holepunch clone lag gate (holepunch-freshness-gate.json,
  verify-holepunch-clone-freshness.mjs) and wire into pretest/docs.
- Extend stock ctx.bareOsHrpcRequest with disk.os replication routes;
  bump hrpc_allowlist_sketch proc to schema 2 with stockRoutes list.
- Security posture: blindRelayAudit; hyper_multisig_trust_pointer schema 2
  + vault multisig continuity env; login/unlock audit hook.
- Syscalls schema 9 alignment (JSON schema, compatibility matrix, conformance
  matrix clock_gettime); boot budget telemetry schema 2 in metrics_live.
- Coreutils hostname -s/--short man/options; rebuild kernel bins/man.
- POSIX + P2P dashboard section in docs/README; handbook/DOCUMENTATION/
  release-checklist/OTA/KERNEL_CONTRACT/PEAR-RUN and related reference updates.
- verify-boot-policy-extension-signer-pins: scan kernel init fragments.

Note: vendor drift section removed from kernel/lib/bare/README.md (intentional).
