docs(mcp): tagged server:NAME form in dev-channels reference

Browse Source 
Claude Code 2.1.x's --dangerously-load-development-channels takes an
allowlist of tagged entries (`server:<name>` or
`plugin:<name>@<marketplace>`), not a bare switch. The instructions
field's push-only-mode message and the inline comment in
`_poll_timeout_secs` both referenced the old bare form. Update both
so an agent or operator reading them lands on the right invocation —
matched against the docs change in [molecule-docs PR #110](https://github.com/Molecule-AI/docs/pull/110).

No behavior change (string-only edits in instructions text + comment).
33/33 tests still pass.
