* fix(github): reliable PR-task association across all launch paths
Three bugs caused inconsistent PR detection for agent-opened PRs:
- StartCreatedSession never called ensureSessionPRWatch
- Push detection bailed out when a pr_number=0 watch existed
- PR watch branch was never updated after agent branch switches
* fix: extract searchPRForExistingWatch to reduce nesting depth
* fix: address review feedback and fix e2e test timeouts
- Fix UNIQUE constraint error when associatePRFromPush was called with
an existing watch (update pr_number instead of creating new watch)
- Add UpdatePRWatchPRNumber to GitHubService interface
- Fix e2e test timeouts: increase budget to 180s, remove unnecessary
clickTab("Changes"), replace 35s hard wait with polling assertion
* fix(e2e): accept both /t/ and /s/ URL patterns in PR detection tests
Task cards in the Done column navigate to /t/<task-id> (task view),
not /s/<session-id> (session view). The toHaveURL assertion must
accept both URL patterns.
