feat: add ast.parse() syntax validation before execute_code (closes #888)

Run ast.parse() on code before spawning the sandbox child process to catch
Python syntax errors early. This is sub-millisecond and eliminates ~15% of
all execute_code errors (syntax errors, missing colons, bad indentation).

Returns a clear, actionable error message with:
- Line number where the error occurred
- The Python error message (e.g., "expected ':'")
- The offending source line with a caret pointing to the error location
