Address Copilot review round 6: lib syntax + 01 refactor + accurate convergence claim

- _lib.ps1: drop stray extra ) in the gh-auth error message so the 'reported:' block closes cleanly.

- 01-request-review.ps1: refactor the two paginated GraphQL calls (state query + reviewRequests page) to use the existing Invoke-GhGraphQL helper from _lib.ps1, matching the 02 refactor in round 4. Removes ~12 lines of duplicated exit-code + errors[] handling.

- SKILL.md description: replace 'zero open Copilot threads' with 'zero threads awaiting the agent's reply (remaining open threads are explicit hand-offs to the human merge owner — escalated declines, design tradeoffs)' to match the documented convergence semantics in 09-convergence.md. Also adds the permission qualifier ('full multi-round autopilot needs Triage/Write; external PR authors get single-iteration mode + manual re-trigger') so the description matches the new Prerequisites > Permissions section.

Up to 10 more rounds before Copilot finally shuts up. You are exhausted. Stop. This skill runs the whole loop for you: auto-triggers Copilot Code Review via GraphQL (no @copilot mention needed), triages every open thread (Copilot, humans, advanced-security) with a fix / decline / escalate rubric, dispatches parallel fix sub-agents that obey the repo build/test/lint conventions, commits one round per iteration, replies+resolves citing the pushed SHA, then re-triggers Copilot until HEAD is reviewed with zero open Copilot threads. You merge a clean PR; the bot ran the marathon. Use when Copilot left comments on your PR and you want them gone without babysitting. Trigger phrases: "address copilot comments", "run a copilot review loop", "fix this PR", "iterate on copilot feedback", "get this PR to green". Repo-agnostic, gh CLI + PowerShell.'
