Add overclock removal to sanitize script
- New step 10/11 removes overclock settings from /boot/firmware/config.txt - Removes over_voltage, arm_freq, gpu_freq lines - Skipped in soft reset mode (preserves for testing) - Distributable image should let users configure via wizard 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
