Adds the *_list partners that the existing *_get tools have been
missing. Same pattern as repo_list — owner allowlisted, capLimit
helper for pagination, next_page surfaced when the page is full.
internal/gitea/issues.go:
- ListIssues(owner, repo, args) hitting
GET /api/v1/repos/{owner}/{repo}/issues with type=issues server-side
so PRs don't leak in (gitea conflates them on this endpoint).
- ListIssuesArgs struct: State, Labels, Since (ISO 8601), Page, Limit.
internal/gitea/workflows.go:
- ListWorkflowRuns(owner, repo, args) hitting
GET /api/v1/repos/{owner}/{repo}/actions/runs.
- Expanded WorkflowRun struct with DisplayTitle, Event, HeadSHA,
HeadBranch, WorkflowID, RunNumber, UpdatedAt, Actor so callers
can pin runs to a commit / branch without a second lookup.
- ListWorkflowRunsArgs: Branch, HeadSHA, Status, Event, Workflow,
Page, Limit. Status/Event 'all' treated as no-filter.
internal/tools/issue_list.go:
- Default state=open, default limit=30 (matches repo_list).
- next_page returned only when len(issues) == limit.
internal/tools/workflow_run_list.go:
- Default limit=10 (most common use is 'what just happened',
not paging).
- Returns runs + total + optional next_page.
Tests: table-driven for both — happy path, empty result, filter
combinations, allowlist rejection. workflow_run_list also asserts
the 'status=all is no-op' behavior (no query param emitted).
