* feat(context): include diffHunk in PR review comment context
Review comments arrived with only path and line, so the code they were
written against was missing from the prompt. Fetch diffHunk in the PR
GraphQL query and render it under the comment as a diff block.
The hunk is PR-authored content, so it goes through sanitizeContent like
the comment body. Comments without a hunk are unchanged.
Fixes#855
* test(formatter): cover outdated review comments with an empty diff hunk
GitHub returns diffHunk: "" (not null) for comments whose line no longer
exists in the diff, so the render guard has to reject empty strings too.
Found running the real query against anthropics/claude-code-action#1025.
GitHub's GraphQL API returns files: null (with no errors entry, and
changedFiles misreported as 0) when a PR's diff is too large to compute.
The unguarded pullRequest.files.nodes dereference in the fetcher crashed
the action with 'TypeError: null is not an object', and the formatter had
the same latent crash on prData.files.nodes.length.
Widen the GitHubPullRequest type to files | null so the compiler enforces
guards, degrade gracefully in the fetcher with a warning, and render the
file count as unavailable (not '0 files') in the formatter.
Fixes#1587
GitHub's GraphQL author field is null when the account behind a
comment, review, PR, or issue has been deleted (the ghost user). The
action typed author as non-null and read author.login directly, so a
single comment from a deleted account threw and was swallowed into a
generic 'Failed to fetch PR/issue data', failing the entire run.
Make author nullable on the four affected types and fall back to
'ghost' at each login read. With the type nullable, tsc flags every
dereference, so all sites are covered.
The formatted_context block sent to the agent omitted labels for both
issues and pull requests, even though the GraphQL queries already
fetched them. This caused agents to incorrectly report "no labels"
when labels existed, breaking any workflow that routes on label state
(e.g., drift-fix routing on drift:* labels in a Drift Watcher pattern).
Changes:
- Add 'PR Labels:' line to PR context output
- Add 'Issue Labels:' line to issue context output
- Both emit 'none' when no labels are present (explicit > omitted)
- Bump labels(first: 1) → labels(first: 100) in both queries; the
previous cap meant only one label would appear even after the
formatter fix
- Update existing tests + add 'with labels' tests for both PR and
issue branches
Discovered while building a GitHub Actions workflow that uses this
action for drift-watcher routing in an internal seed framework
(joshpayne-joby/slim-routines#6). The agent self-diagnosed the gap
by inspecting this action's source — a satisfying full-loop.

When a PR originates from a fork, `git fetch origin <branch>` fails
because the branch only exists on the fork's remote.
Fix: detect cross-repository PRs via the `isCrossRepository` GraphQL
field and fetch using `pull/<number>/head:<branch>` refspec instead,
which is the standard GitHub mechanism for accessing fork PR branches.
Changes:
- Add `isCrossRepository` and `headRepository` to PR GraphQL query
- Add corresponding fields to GitHubPullRequest type
- Branch checkout uses pull ref for fork PRs
- Update test fixtures with new fields
