fix(claude): one constant mcpctl MCP entry instead of one per project

Browse Source 
`config claude` named the `.mcp.json` entry after the project, and the file is
merged rather than rewritten — so configuring a second project left the first
one mounted alongside it. Every project you had ever configured stayed
connected, with duplicate tool names and nothing saying which was active.

The entry is now always `mcpctl`, and switching rewrites what sits behind that
name. Claude Code can reconnect an existing MCP server from inside a session, so
a switch lands without restarting the app, and the tool prefix stays stable
across switches. Entries an older CLI wrote are retired on the next run —
recognised by the pairing that makes retiring them safe: our command, named
after the very project it bridges to. A hand-configured server is never touched.

The shaping lives in config/claude-mcp.ts as pure functions so the merge,
migration and active-project detection are unit-tested rather than inferred from
a command's side effects.

Also brings two parity gaps in line with `config opencode` / `config prime-agent`:
--dry-run, and --skip-marker for when the caller must not re-scope the directory
it runs in.
