Closes#339.
This change adds named volume support to container, providing volume
management CLI commands - `create, delete, list and inspect`. The
implementation uses EXT4 block-based persistent storage with a new
`VolumesService` actor for thread-safe operations, integrates seamlessly
with the existing container mount system through a new `.volume`
filesystem type, and provides atomic volume operations with XPC-based
API communication. Volumes are stored in isolated directories with
configurable sizes (default 512GB) and include proper cleanup and
container usage tracking for safe deletion.
Example Usage:
```
# Create a volume
container volume create mydata
# Use volume in container
container run -v mydata:/data alpine
# List volumes
container volume list
# Inspect volume details
container volume inspect mydata
# Clean up
container volume rm mydata
```
This PR resolves a race condition when removing a container immediately
after stopping it, caused by the `stop` command returning before the
container fully transitions to the stopped state (#130).
**Changes:**
- Enhanced `TestCLIRmRace.swift` with robust test logic and helper
methods (`containerExists`, `safeRemove`).
- Improved error handling to distinguish race conditions from successful
removals.
- Added exponential backoff retry logic for cleanup operations.
- Updated `CLITest.swift` with missing `doRemove` method.
- Fixed `BuilderStart.swift` to handle `.stopping` case.
- Improved error messages with container ID for better debugging.
**Testing:**
- ✅ All tests pass (`make test`, `make integration`).
- ✅ Verified on macOS 26.
- ✅ Race condition test validates success and failure scenarios.
- ✅ Code formatted (`make fmt`).
Hopefully, this will pass the integration tests on GitHub.
