feat(plugins): make Claude Code and Codex installs self-contained (#7514)

Ship Claude Code and Codex from one release-pinned npm artifact with bundled runtime dependencies, extraction-only MCP qualification, plugin-aware recovery, and synchronized release metadata.

Integrates #2815 and the original proposal #1977. The original commits remain available on the PR branch; retain their author and assistant credit in this squash.

Validation: required CI passed, real Codex/Claude loading verified, and reviewed packaging/recovery findings addressed.
