zeekay d5f07ec514 feat(shell): add shell detection to only expose user's active shell

- Add shell_detect.py module with comprehensive shell detection:
  - Detects login shell from passwd/Directory Services
  - Detects invoking shell by walking parent processes
  - Prefers Homebrew shell paths on macOS
  - Supports override via HANZO_MCP_SHELL and HANZO_MCP_FORCE_SHELL

- Update hanzo-tools-shell to only include detected shell in TOOLS list
  - HANZO_MCP_ALL_SHELLS=1 to expose all shells
  - get_shell_tools() now supports shell_override parameter

- Add CLI options to hanzo-mcp:
  - --shell: Specify shell by name or path
  - --all-shells: Expose all shell tools
  - Updated --force-shell to include fish and dash

- Bump hanzo-tools-shell to 0.6.0 (published to PyPI)
- Bump hanzo-mcp to 0.10.36

Detection order: HANZO_MCP_SHELL > HANZO_MCP_FORCE_SHELL > CLI --shell >
invoking shell > login shell > $SHELL

hanzo-tools-shell

Shell execution tools for Hanzo MCP with DAG support and Shellflow DSL.

Installation

pip install hanzo-tools-shell

Tools

dag - DAG Execution Engine

Execute commands with directed acyclic graph semantics.

# Serial execution (default)
dag(["ls", "pwd", "git status"])

# Parallel execution
dag(["npm install", "cargo build"], parallel=True)

# Mixed DAG with parallel blocks
dag([
    "mkdir -p dist",
    {"parallel": ["cp a.txt dist/", "cp b.txt dist/"]},
    "zip -r out.zip dist/"
])

# Tool invocations
dag([{"tool": "search", "input": {"pattern": "TODO"}}])

# Named nodes with dependencies
dag([
    {"id": "build", "run": "make build"},
    {"id": "test", "run": "make test", "after": ["build"]},
])

zsh - Primary Shell with Shellflow DSL

Execute shell commands with optional Shellflow syntax.

# Simple command
zsh("ls -la")

# Shellflow DSL syntax
zsh("mkdir dist ; { cp a dist/ & cp b dist/ } ; zip out")

# With shell parameter
zsh("echo $BASH_VERSION", shell="bash")

Shellflow Syntax:

A ; B - Sequential execution
{ A & B } - Parallel execution
A ; { B & C } ; D - Mixed DAG

ps - Process Management

Monitor and control background processes.

ps()                     # List all processes
ps(id="abc123")          # Get specific process
ps(kill="abc123")        # Kill process (SIGTERM)
ps(logs="abc123", n=50)  # Last 50 lines of output

Additional Tools

shell - Smart shell (zsh > bash fallback)
bash - Explicit bash execution
npx - Node package execution with auto-backgrounding
uvx - Python package execution with auto-backgrounding
open - Open files/URLs in system apps
curl - HTTP client without shell escaping issues
jq - JSON processor
wget - File/site downloads

Auto-Backgrounding

Commands that exceed the timeout (default 60s) are automatically backgrounded:

dag(["long-running-command"], timeout=30)
# If command exceeds 30s, it continues in background
# Use ps --logs <id> to view output

Performance

Shellflow DSL is optimized for high throughput:

Simple commands: ~7M ops/sec
Sequential: ~2.2M ops/sec
Mixed DAG: ~100k ops/sec
