Caleb Leak 055e7a561f fix(beads-mcp): prevent subprocess stdin inheritance breaking MCP protocol ...

When running as an MCP server, subprocesses must not inherit stdin because
MCP uses stdin for JSON-RPC protocol communication. Inherited stdin causes
subprocesses to block indefinitely waiting for input or steal bytes from
the MCP protocol stream.

Added stdin=subprocess.DEVNULL (or asyncio.subprocess.DEVNULL for async)
to all subprocess calls:
- server.py: _resolve_workspace_root() git subprocess
- tools.py: _resolve_workspace_root() git subprocess
- bd_client.py: _run_command(), _check_version(), add_dependency(),
  quickstart(), and init() async subprocess calls
