feat(hooks): add sisyphus-task-retry hook for auto-correction

Helps non-Opus models recover from sisyphus_task call failures:
- Detects common errors (missing params, mutual exclusion, unknown values)
- Injects retry guidance with correct parameter format
- Extracts available options from error messages
- Disableable via config: disabledHooks: ['sisyphus-task-retry']
