João Salavisa b8a09bc5ea fix(github): pick allowed merge method so squash-only repos stop 405ing (#999)
* fix(github): pick allowed merge method so squash-only repos stop 405ing

The merge button sent an empty merge_method to GitHub, which defaults to
"merge" regardless of repo settings — squash-only / rebase-only repos
returned 405 "Merge commits are not allowed on this repository". The
backend now resolves an empty method to the first allowed one via a new
GetRepoMergeMethods endpoint (5-min cache), and the frontend renders a
GitHub-style split button so users can pick among the allowed methods.

* fix(github): address PR #999 review feedback

- pr-merge-button: extract repo-methods fetch to useRepoMergeMethods
  hook (Claude bot); hide button while methods are loading so the
  primary label doesn't flicker (Claude bot); drop e.preventDefault on
  dropdown items so Radix closes the menu on selection (Greptile P1).
- gh_client / pat_client: treat missing allow_* fields as false instead
  of true so a permission-gated response can't pick a disallowed merge
  method (cubic P2).
- service.MergePR: only overwrite mergeMethod when pickDefaultMergeMethod
  returns non-empty, so a degenerate all-false config falls through to
  GitHub's default with the real error (Claude bot).

* fix(github): don't hide merge button on lookup failure

Round-2 PR feedback (Claude, Greptile, CodeRabbit, cubic): the
`if (!methods) return null` guard added in the previous round to
avoid label flicker turned a transient repo-methods lookup failure
into a permanent UI lockout — the button would stay hidden until
unmount/remount.

- pr-merge-button: revert the null-guard; treat null as "use backend
  resolver", render the plain primary button without a dropdown.
- use-repo-merge-methods: add a 5-min frontend TTL to match the
  backend cache so admin merge-strategy flips are visible without a
  page reload. Catch block now triggers a rerender, and co-waiting
  consumers attach both fulfilled/rejected handlers to avoid silent
  rejection swallowing.

* test(github): cover useRepoMergeMethods + silence rejection warning

Round-3 PR feedback (Claude):

- Swallow rejections in the originating fetch chain instead of
  rethrowing, so the first consumer's promise never escapes the hook
  as an unhandled rejection. Coalesced consumers already re-render to
  null, which is the same state a fresh "not loaded" call would show.
- Add use-repo-merge-methods.test.ts covering: null-on-missing-params,
  loading then resolution, cache hit on remount, concurrent-fetch
  coalescing, retry-on-failure (no cache poisoning, no unhandled
  rejection), and TTL-expiry refetch via fake timers.

* test(github): cover httpGetRepoMergeMethods error branches

Round-4 PR feedback (Claude): the new endpoint had only happy-path
coverage. Add tests matching httpMergePR's existing shape:

- nil client → 503 (ErrNoClient)
- GitHubAPIError{404} → 404
- generic upstream error → 500
