Ramon Nogueira f164f992e0 feat(deepagents): add snapshot/start/stop lifecycle to LangSmithSandbox (#479 )

## Summary

Expose the new LangSmith sandbox snapshot and lifecycle APIs (landed in
`langsmith@0.5.20`) through the `LangSmithSandbox` wrapper.

- New methods on `LangSmithSandbox`: `start()`, `stop()`,
`captureSnapshot()`
- `LangSmithSandbox.create()` now accepts `snapshotId` (preferred) or
`templateName` (deprecated); throws if neither is provided
- Re-export upstream types as `LangSmithSnapshot`,
`LangSmithCaptureSnapshotOptions`, `LangSmithStartSandboxOptions`
- Bump `langsmith` peer dep to `>=0.5.20`
- Update the example to boot from `LANGSMITH_SANDBOX_SNAPSHOT_ID`

## Test plan

- [x] Unit tests: added coverage for `start()`, `stop()`,
`captureSnapshot()`; 41/41 pass
- [x] Type-check clean
- [x] Dev smoke test against `dev.api.smith.langchain.com` — create from
snapshot, execute, stop, start, execute after restart all working
