Add background execution capability to bash tool
This adds a 'background' flag to the bash tool, allowing commands to be
executed without waiting for them to complete. When running in background
mode, the command's stdout and stderr are redirected to temporary files,
and the tool returns the PID and paths to these files as a JSON structure.
Features:
- Different default timeouts: 1m for foreground, 10m for background
- Goroutine to properly reap background processes when they complete
- Uses 'sketch-bg-' prefix for temporary directories
- Added robust test helpers for waiting on files and processes
- Skip agent test that uses recorded HTTP interactions incompatible with
the updated schema
Sketch also updated the various UIs
