Add configurable logging system with DEBUG level and file output

[Copilot]

Implements a Python logging system to replace scattered print() statements, enabling debug-level verbosity control and optional log file generation.

Changes

New logging module (logger.py)

• Singleton pattern with colored console output (red=ERROR, yellow=WARNING, cyan=INFO, gray=DEBUG)
• File handler with timestamps, always captures DEBUG regardless of console level
• Helper functions: debug(), info(), warning(), error(), critical()

Command-line arguments

• --log-level {DEBUG,INFO,WARNING,ERROR,CRITICAL} (default: INFO)
• --log-file <path> for persistent logs
• --no-color to disable ANSI codes

Integration

• Updated main.py and compile.py to use logger instead of print()
• Added DEBUG messages for arguments, file lists, and processing details
• Maintains existing message format ([ANALYZER], [AUTOFIX], [COMPILE])

Testing

• 8 unit tests covering singleton pattern, log levels, file I/O, and formatting

Usage

# Debug mode with detailed output
./main.py --analyze /path/to/kernel --log-level DEBUG

# Persistent logging
./main.py --fix --json-input json/checkpatch.json --log-file logs/fix.log

# Quiet mode (warnings/errors only)
./main.py --analyze /path/to/kernel --log-level WARNING

# In code
import logger
logger.debug("[MODULE] Detailed troubleshooting info")
logger.info("[MODULE] Normal operation message")
logger.error("[MODULE] Something failed")
