Add runner execution observability and lifecycle hardening for self-hosted
GitHub Actions runners, including:
- scheduled artifact cleanup job for cached runner tarballs/templates
- workflow_job in_progress handling to mark executions as running
- safer cleanup failure handling and non-functional server fallback
- persisted workflow job HTML URLs with execution "Open" links in UI
- configurable runner group name sync (UI + provisioning + GitHub API)
- webhook events persistence and auto-fix for missing required events
- strict enum/status checks and related model cast/query improvements
Also includes migrations and expanded feature/unit coverage for webhook,
provisioning, cleanup, and runner group/event sync behaviors.
Add configurable `capacity_wait_timeout` to runner configs and use it in
`ProvisionGithubRunnerJob` to re-dispatch jobs while at capacity, preserving
initial wait start time and stopping after timeout.
Improve runner provisioning by caching an extracted runner template and copying
it into new runner directories.
Update Livewire GitHub Runners UI to lazy-load accessible repositories via
`wire:init`, track loading state, add timeout input, and remove preinstall
binary action.
Add/extend feature tests for capacity retry timeout behavior and deferred
repository loading.
