feat(pull-request): add native Gitea tracking and reviews

[kalvenschraut]

Gitea repositories need the same built-in PR inbox, linked-thread tracking, review, and lifecycle flow as the existing hosts. Map Gitea REST responses directly into T3’s provider models for lists, detail, summaries, activity, checks, comments, reviews and replies, diffs, reviewer/label changes, merge methods, branch updates, and close/reopen.

Read full files at immutable head and merge-base revisions, keep paths inside the selected repository, preserve pagination across server-imposed page limits, and retain native review conversations. Declare unsupported capabilities explicitly: draft/ready writes, auto-merge controls, reactions, comment editing, workflow approval, revert PRs, and host-side text search. This uses Gitea directly and requires no GitHub protocol emulation.

Validation: focused provider/transport and existing-host regression tests, server typecheck, and live adapter checks on Gitea 1.27.3 against the designated test repository. Live checks covered list/detail/summary/activity, diffs/full files, comments, labels, self-review, and close/reopen; temporary branches and labels were cleaned up. End-to-end settle-on-merge passed: T3 merged a test PR into a temporary base branch, then emitted thread.settled and an accepted server:auto-settle receipt (sequence 4) for its linked thread. The settlement event followed linking by about one second. No test merge targeted the repository’s main branch.

Final stack validation at 256fd6fe5: 228 focused tests passed, followed by 61 API/workflow cases and the final team-recovery regression; server typecheck and targeted lint passed. The live settle-on-merge E2E previously passed with fixture cleanup. Companion Gitea backend and focused integration tests passed, including native revert across all five merge styles.

Implementation: Codex (GPT-6 and GPT-5.6 Sol). Sensitive review: GPT-6 Astra. Planning/design review: Claude Fable 5.1 via Claude Code CLI.

Provider mapping, registration, and documentation apps/server/src/pullRequest/GiteaPullRequestProvider.ts, apps/server/src/pullRequest/GiteaPullRequestProvider.test.ts, apps/server/src/pullRequest/PullRequestProviderRegistry.ts, docs/user/source-control.md	Maps Gitea data and errors to provider contracts, calculates permissions, registers the provider and API layers, and documents supported and unsupported Gitea features.

Estimated code review effort: 5 (Critical) | ~90 minutes

Merge Risk: 🟡 Moderate · up to 75736

Pull requests with many inline review comments can silently show incomplete conversations. This should be fixed before merge so reviewers do not miss discussion.

Learning: For Gitea v1.27.3, `GET /repos/{owner}/{repo}/pulls/{index}/reviews/{id}/comments` is unpaginated. `GetPullReviewComments` calls `convert.ToPullReviewCommentList`, which returns all comments in the review conversation. Do not add client-side pagination based on response row count for this endpoint, because repeated requests return the same complete list. In `apps/server/src/pullRequest/GiteaPullRequestProvider.ts`, a `listReviews` failure is represented as truncated activity.

Stack dependency satisfied in rtvision: the combined integration includes #16's affirmative action metadata, #20's review pagination, and #23's warning-status correction.

The original PR branch is unchanged. Those fixes must accompany this feature when preparing a standalone upstream slice, since the early snapshot still has permissive defaults for missing permission metadata, single-page review comments, and warning-as-neutral checks.

Integration: a3ad93268, tree 9e13dd0812b8743ef76d4b8adca2f683317fc9e5. All original feature branches are preserved. Implementation/review: Codex (GPT-6); independent approval for the exact commit and rtvision destination: Claude Fable 5.1 through Claude CLI.
