Opt-in (mcpSyncEnabled, default OFF; routes 403 until on). Review fixes:
- codex TOML read/validated with smol-toml: CRLF, inline tables and
command-less tables no longer yield a duplicate [mcp_servers.x]; the new
text is re-parsed before writing
- null-prototype tables and own-key checks; unsafe names ignored at every level
- servers switched off in their own CLI (codex/opencode/antigravity) are not copied
- only CLIs that are installed or already have a config file take part
- files receiving env/headers are left 0600; symlinked configs are written through
- one apply at a time (409), unique tmp files cleaned on failure, failed status
- routes set real HTTP status codes; api-reference section; format type single-sourced

Adds capabilities.mcpConfig to the CLI registry (Claude, Gemini, Codex,
OpenCode), an additive src/mcp-sync.ts, GET/POST /api/mcp-sync and a
Settings > Agents & CLIs control. Never edits or removes an existing
server; backs up each file it changes; reports conflicts.
