## Zusaetzliche Runner-Guidelines (framework-agnostisch)
- **Testnamen-Konvention:** Runner sollen eine konsistente, dokumentierte Full-Name-Bildung verwenden (z. B. `Parent/Subtest`), inklusive Mehrfach-Nesting. Diese Konvention muss in `results.*`, `parse_test_output` und `collect_failed_locations` uebereinstimmen.
- **TSamNearest-Prioritaet:** Falls moeglich, gelten folgende Regeln: Test-Block > Describe/Context-Block > File-Command. Das Verhalten muss getestet werden (Cursor im Test, zwischen Tests, ausserhalb von Describe/Context).
- **Reporter-Payload-Schema:** Wenn ein Custom-Reporter verwendet wird, soll dessen JSON-Payload dokumentiert und stabil sein (z. B. `{ name, status, file, location, output }`), damit Parser/Quickfix/Detail-Output konsistent bleiben.
- **Failed-Only-Logik:** Failed-Only muss auf den letzten Fehlermeldungen basieren und nur die fehlerhaften Tests erneut ausfuehren. Die Pattern-Strategie (z. B. Titel-only vs. Full-Name) muss getestet werden.
- **CI-Installations-Snippet:** Die Neovim-Installation in CI soll als „authoritative snippet“ behandelt werden und in Runner-Repos 1:1 uebernommen werden.

## Features
- Detects Jest test files (`*.test.*`, `*.spec.*`).
- Activates only when the nearest `package.json` lists `jest` in dependencies or devDependencies.
- Finds nearest `test`/`it` within `describe` blocks.
- Builds `npx jest` commands for nearest, file, all, and failed-only runs.
- Streams results via a custom Jest reporter using `onTestCaseResult`.
