- escapePath now returns an error when paths contain dot-segments
(".", "..") instead of silently rewriting them. This prevents
subtle API misses where callers pass "foo/../bar" expecting to
hit "bar" but the old code produced "foo/bar".
- Uses path.Clean for canonical form after validation.
- CommitStatus.Description for check runs is now empty string
instead of the raw conclusion enum. The conclusion is already
captured in the Status field via mapCheckRunStatus; storing it
again in Description was semantically inconsistent with commit
statuses where Description carries a human-readable narrative.
- Removed unused derefString helper.
- Added tests for escapePath valid paths, dot-segment rejection,
and GetFileContentAtRef dot-segment error propagation.
- Separate maxPages into maxFilesPages and maxCheckRunPages constants
for clarity (sonnet MINOR #1)
- Add parallel to CheckRunConclusions subtests (sonnet MINOR #2)
- Add TestGetCommitStatuses_CheckRunsErrorAfterStatusesSucceed test
covering check-runs 500 after statuses succeed (sonnet MINOR #2)
- Expand mapCheckRunStatus doc comment with full mapping rules including
cancelled/skipped/neutral rationale and unknown value behavior
(sonnet MINOR #3, gpt MINOR #1)
- Expand GetPullRequest doc comment to mention error types returned
(sonnet NIT #4)
- Add inline comment on Description field clarifying it holds raw
conclusion value (gpt NIT #3)
