Fixed the undefined: prWithReviewers compile error — added prResponse struct and prWithReviewers helper in prs.go, and updated Get to return reviewers alongside the PR
Registered PRSettingsHandler in router.go with routes for /default-reviewers, /default-description, and /excluded-files under /{owner}/{repo}
Frontend (prs.ts):
useDefaultReviewers / useAddDefaultReviewer / useRemoveDefaultReviewer
useDefaultDescription / useUpdateDefaultDescription
useExcludedFiles / useUpdateExcludedFiles
RepoSettingsPage.tsx — three new fully functional sections:
Default reviewers — avatar list with add/remove, auto-assigned on PR creation
Default description — Markdown textarea pre-fills new PR bodies
Excluded files — glob patterns textarea, excludes matched files from PR diffs
