Add CodeSandbox as a new sandbox cloud provider for running AI agents.
CodeSandbox features:
- Firecracker microVMs with ~2 second start times
- SDK/CLI-based exec (no SSH)
- Free tier: 40 hours/month on Build plan
- Secure isolated environments
Implementation:
- Created codesandbox/lib/common.sh with SDK wrapper functions
- Implemented 3 agent scripts: claude, aider, openclaw
- Added CodeSandbox to manifest.json clouds
- Created matrix entries (3 implemented, 12 missing)
- Updated test/record.sh to list as non-recordable CLI cloud
- Added codesandbox/README.md with usage instructions
The implementation follows the existing pattern from e2b and modal,
using Node.js SDK (@codesandbox/sdk) for sandbox lifecycle management.
