* fix: purge expired thread_wakeup crons
One-shot wakeup crons set an end_time that stops re-firing but the cron
row is never deleted, so dead rows accumulate (86 in prod). Add a purge
that deletes thread_wakeup crons past their end_time, called
opportunistically before scheduling a new wakeup, plus a one-time
backfill script. Conservative: matches only kind=thread_wakeup with a
past end_time.

* feat: move github workflows to gh cli
Use LangSmith proxy auth to support gh-driven GitHub workflows while removing custom GitHub wrapper tools.
* docker ignore + snapshot and docker image updates
* updated image and instructions
* removing open_pr if needed after agent call
* feat: migrate LangSmith sandbox creation to snapshot API
Replaces the template-based sandbox flow (DEFAULT_SANDBOX_TEMPLATE_NAME /
DEFAULT_SANDBOX_TEMPLATE_IMAGE) with the new snapshot-based flow.
- New required env var DEFAULT_SANDBOX_SNAPSHOT_ID (UUID of a pre-built
LangSmith snapshot; build out-of-band via UI or SandboxClient.create_snapshot)
- Optional DEFAULT_SANDBOX_SNAPSHOT_FS_CAPACITY_BYTES overrides the root FS
size at boot (default 32 GiB)
- Startup-time validation via a FastAPI lifespan hook: the server refuses
to boot with a clear ValueError if SANDBOX_TYPE=langsmith and
DEFAULT_SANDBOX_SNAPSHOT_ID is unset, so failures surface in boot logs
rather than on the first thread
- Reconnect-to-existing-sandbox path unchanged
- Docs (INSTALLATION.md, CUSTOMIZATION.md) updated to describe the new
snapshot workflow
* fix: format create_sandbox_snapshot.py to pass ruff
