Closes#3.
Adds an "Actions" tab to the repository view, surfacing Forgejo Actions runs and (experimentally) their jobs, steps, and logs.
## What's in this branch
1. ~~**`chore: point ForgejoKit at local checkout for Actions PR`** — temporary `XCLocalSwiftPackageReference` so the feature commit compiles against the unreleased ForgejoKit changes. Drop this commit before merge and replace with `chore: bump ForgejoKit to <new version>` once the ForgejoKit PR ships in a release.~~
**`chore: update ForgejoKit to released version 0.4.0`** + **`chore: add ForgejoKit 0.4.0 to Package.resolved`** — switches from local path override to a remote pin at `secana/ForgejoKit` `0.4.0`.
2. **`feat: add Actions tab to repository view`** — the actual feature.
## UI scope
- New `Actions` tab, shown only when `repository.hasActions == true`.
- Runs list with All / Running / Success / Failed filter, pagination, pull-to-refresh, empty state.
- Run detail with header, metadata (workflow file, event, trigger user, started/duration — zero-Date suppressed), and an experimental Jobs section.
- Job view with collapsible step rows; logs lazy-load on expand via `logCursors`.
- "Open in browser" toolbar item using each run's `html_url`.
## Experimental jobs/steps view
Forgejo's `/api/v1` doesn't expose jobs, steps, or step logs for a run. This PR opts into ForgejoKit's experimental `fetchRunView` (backed by Forgejo's web-UI route) so we can render a GitHub-Actions-style view today. The Jobs section and Steps screen are explicitly labelled "Experimental" in the UI, and a footer notes the output may change between Forgejo versions. Happy to drop this section if you'd rather ship public-API only first.
## Defensive handling
- Forgejo serialises an unset `time.Time` as `0001-01-01T00:00:00Z` (showed up as "Started 56 yrs, 4 mths" / "Duration 493 906h" on a cancelled run). Sanitised display helpers suppress any pre-2000 date.
- The experimental `fetchRunView` resolves Forgejo's `RedirectToLatestAttempt` server-side before POSTing, so attempts with non-zero attempt numbers work. (Without this, Forgejo returns 500 "task with job_id N and attempt 0: resource does not exist".)
## Tests
- Unit: `WorkflowRunFilterTests`, `WorkflowStatusIconTests` (filter mapping, status enum compatibility against Forgejo's documented values, status icon mapping, run helpers, zero-date guard).
- UI: `ActionsUITests` (read-only smoke test).
