feat: add TypeScript module for Python run configuration

[devin-ai-integration]

Summary

This PR adds a new TypeScript/Node.js module that migrates the TRunConfiguration class and TPythonControl.Run/Debug methods from the Delphi codebase (Source/cPyControl.pas and Source/cPySupportTypes.pas) to TypeScript.

The module provides:

• RunConfiguration interface with script path, arguments, working directory, and environment variables
• PythonRunner class with run() and debug() methods using Node.js child_process.spawn()
• DebuggerState and PythonEngineType enums matching the original Delphi types
• Custom error classes for validation (missing Python, missing script, invalid directory)
• Event emitter pattern for stdout/stderr/exit/state changes
• Output file writing support

The debug functionality currently uses Python's built-in pdb module and is structured to support future DAP (Debug Adapter Protocol) integration.

Review & Testing Checklist for Human

• Test with actual Python scripts - No unit tests are included. Manually verify that run() and debug() work correctly with real Python scripts on your target platform
• Verify cross-platform behavior - The pause() and resume() methods use Unix signals (SIGSTOP/SIGCONT) which are no-ops on Windows. Confirm this is acceptable
• Review breakpoint handling - The BreakpointInfo interface is defined in DebugOptions but is not actually used in buildDebugArgs(). Determine if breakpoint support should be implemented or removed
• Validate debug experience - The debug mode uses pdb which provides basic debugging. Verify this meets requirements or if more sophisticated debugging is needed

Test Plan

1. Create a simple Python script (e.g., print("hello"))
2. Use the module to run it: const result = await run({ scriptPath: '/path/to/script.py' })
3. Verify stdout contains expected output
4. Test debug mode with initStepIn: true to confirm pdb launches correctly

Notes

• Build passes: npm run build succeeds
• Lint passes: npm run lint succeeds (with TypeScript version warning)
• The module is placed in ts-src/ directory as a new TypeScript project within the repo
