Merged
Conversation
Add bashkit-cli crate with command line interface:
- bashkit -c 'command' - Execute command string
- bashkit script.sh - Execute script file
- bashkit --help / --version
Features:
- Proper exit codes
- stdout/stderr handling

Add ExecutionLimits and ExecutionCounters for resource control: - Maximum command count (fuel model) - Maximum loop iterations - Maximum function call depth - Timeout support (Duration) Integration tests verify limit enforcement for: - Command limits with short-circuit on exceed - Loop iteration limits in for/while/until - Function recursion depth limits Also adds TODO comment about parser keyword ambiguity issue. https://claude.ai/code/session_01A16cD8ztbTJs2PB2iHe1Ua
Add two new filesystem implementations for advanced use cases: OverlayFs: Copy-on-write filesystem - Layers writable upper on read-only lower - Tracks deletions via whiteouts - Supports recreation of deleted files - Merges directory listings from both layers MountableFs: Multiple mount points - Mount filesystems at specific paths - Nested mount support (longest prefix match) - Mount points visible in directory listings - Cross-mount copy/rename support https://claude.ai/code/session_01A16cD8ztbTJs2PB2iHe1Ua
