feat: auto-review PRs on opened / ready-for-review (#1325)
* feat: auto-review PRs on opened / ready-for-review

Trigger Open SWE Review on `pull_request` actions `opened` and
`ready_for_review` against the canonical reviewer thread (no need to
request open-swe[bot] as a reviewer). `converted_to_draft` now also
flips watch=False on the existing reviewer thread.

Draft PRs are gated by a tri-state user setting on the profile:
inherit team default, always on, or always off. The team-wide
`review_draft_prs` setting is the org-wide default; each user can
override it in My Settings.

External contributors with no Open SWE profile fall back to the team
default.

* fix: PR review comments — auth source + draft-aware watch toggle

- `process_github_pr_ready` now dispatches with `source="github"` so the
  auth resolver finds the bot token persisted on the thread. The previous
  `source="github_auto"` fell through to the email-based path in non
  bot-token-only deployments and failed with a missing-user-email error.

- `converted_to_draft` no longer unconditionally clears `watch`. When the
  PR author's effective `review_draft_prs` setting is on, watch stays on
  so subsequent pushes still trigger re-reviews while the PR is in draft.

* feat(reviewer): skip "no issues found" comment on empty re-reviews

A re-review run with no new findings to surface no longer posts another
"Open SWE Review: No issues found" comment on the PR. The "no issues"
summary now only appears on the first review of a PR — matching Devin's
behavior, where subsequent reviews are silent unless there's something
new to flag.

Resolved-thread reconciliation and ``last_reviewed_sha`` persistence
still happen on the skipped path, so findings the user just fixed still
get their GitHub threads marked resolved, and the next push event sees
an up-to-date dedup SHA.
