agentpr/watchpr already propagated command errors to a non-zero exit, but that behaviour had no regression coverage and the root command was not constructible outside main(). watchpr also fired a spurious conflict alert because Gitea computes mergeability asynchronously and can briefly report mergeable=false right after a push. The docs additionally printed the AppRole role_id literal UUID. - Extract newRootCmd() in both cmd/agentpr and cmd/watchpr so main() only runs Execute and exits non-zero on error; add tests asserting Execute returns an error for a bad PR ref / malformed --repo / no args. - Debounce mergeability loss in MeaningfulChange: only alert when mergeable=false persists across two consecutive polls (both prev and cur false, still open); update the table test for one-poll-false (benign), false-persisting (alert), and recovered false->true (benign). - Refer to AGENT_APPROLE_ROLE_ID by env var in README.md/AGENTS.md without printing the literal role_id; keep the code default and env override.
