What's being changed (if available, include any code snippets, screenshots, or gifs):

Clarifies that write_agent accepts exactly one targeting selector, that explicit IDs must identify known running or idle agents, and that terminal or non-resumable agents should be replaced with a fresh task instead of retried. It also documents correcting selector validation failures once rather than repeating malformed calls.

Hi @jessesanford, thanks for raising a PR

Could I just clarify that you're waiting for a review of github/copilot-cli#5210, from a different team? It seems like this PR wouldn't be correct if the outcome of that review is that the functionality itself needs a bugfix. Thank you!
