feat(pull-requests): search native Gitea pull requests

[kalvenschraut]

Gitea pull-request search now uses the native issue search endpoint with type=pulls, then hydrates matching pull requests into T3's existing models. Pagination preserves the search endpoint's ordering and applies state and involvement filters after hydration.

Focused coverage includes capped pages, invalid rows, state filtering, and cursor advancement. Integrated focused tests, server typecheck, and targeted lint pass.

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.

Model: GPT-5.6 Luna (max), integrated by GPT-6 Astra. Harness: Codex.

📝 Walkthrough

Walkthrough

Gitea pull-request listing now supports optional issue-search queries. Search results are validated, hydrated through pull-request endpoints, filtered by state and involvement, paginated with cursor offsets, and bounded by the existing safety limit.

Changes

Gitea pull-request search

Layer / File(s)	Summary
Search contracts and URL construction apps/server/src/pullRequest/GiteaSearch.ts, apps/server/src/pullRequest/GiteaSearch.test.ts	Defines validated search issue data, state mapping, encoded search paths, authored-user filtering, and safe issue-number extraction.
Search listing and provider integration apps/server/src/pullRequest/GiteaPullRequestApi.ts, apps/server/src/pullRequest/GiteaPullRequestProvider.ts, apps/server/src/pullRequest/GiteaPullRequestApi.test.ts	Routes non-empty queries through paginated Gitea search, hydrates results with bounded concurrency, applies shared filters, preserves cursor offsets, enforces pagination limits, and advertises search support.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to d2fcc

Gitea pull-request search can fail completely when one matching pull request returns incomplete data, hiding otherwise valid results. This should be fixed before merge while preserving fatal handling for transport and authorization errors.

Effect.forEach listing path to convert only incomplete or invalid hydrated pull
data into null so that row is skipped, while preserving fatal propagation for
transport and authorization failures. Add a focused test alongside the existing
listing tests covering an incomplete hydrated pull response together with a
valid result and asserting the valid result remains.
