v5.12.1 — Codex integration & release hardening

Patch release that resyncs npm + ClawHub + the repo and adds first-class OpenAI Codex support.

Added

• OpenAI Codex integration — project-scoped .codex/config.toml registers the Network-AI MCP server (stdio) for the Codex CLI and IDE extension. One-command install:

  codex mcp add network-ai -- npx -y -p network-ai network-ai-server --stdio
  

  New "Use with OpenAI Codex" section in the README and a Codex block in QUICKSTART.
• PRIVACY.md — explicit privacy policy: no data collection, no telemetry (opt-in BYOT only), no call-home; all state is stored in local files the operator controls.

Fixed

• CI npm publish race — the publish job now serializes per tag ref (concurrency) and treats a 403 as success when the version already exists on the registry, eliminating the E403 that occurred when two tag runs published the same version concurrently.
• package.json metadata — removed the leading ./ from the four bin paths and set repository.url to the git+https://… form to silence npm publish warnings.

Changed

• Version bump 5.12.0 → 5.12.1 across package.json, skill.json, openapi.yaml, the README release badge, the Claude Code plugin manifests, and documentation headers.
• Corrected stale test counts to 3,269 tests across 33 suites.
• Sharper Claude Code plugin descriptions in the plugin + marketplace manifests.
