465d22166d Commit: System Optimization & Unified Architecture 
Unified BIOS Patching: Merged management for SCPH-5500, 5000, and 3500.

New Hardware Bypass: Added a physical switch option for SCPH-7000 to disable the BIOS patch on-the-fly.

Compilation Feedback: Integrated #pragma messages to display during the build process.

Code Documentation: improved technical clarity.

10a054d60c BIOS Patching: Finalizing ISR-based logic for timing stability 
Re-implemented Hardware ISR (INT0/INT1): Restored interrupt-driven pulse counting to eliminate polling jitter. Tests confirmed that at 16MHz, software polling is too inconsistent for reliable DATA OVERDRIVE synchronization.
Mechanism Freeze: The core logic (Stabilization -> Silence Detection -> ISR Counting -> Injection) is now finalized and stable.
Portability Note: Maintained a clean structure to allow future non-ISR porting, although the ISR version remains the mandatory standard for ATmega328P @ 16MHz performance.

0ff2612c7c Refactor: Optimization of board detection, injection logic, and global nomenclature 
- Board Detection: Added 300ms stabilization delay to filter PU-7/20
  power-up noise and sync with PU-22+ oscillating signals.
- Injection: Added conditional break to allow single-region selection
  and updated WFCK modulation for 7.3/14.6 kHz compatibility.
- Logic: Optimized sector filtering using bitmask (0xD0) and improved
  hysteresis tracking for Standard and SCPH-5903 models.
- Code Quality: Standardized nomenclature (subqBuffer, hysteresis,
  pulseCounter) and added comprehensive English documentation.
- Performance: Reduced binary size by optimizing loops and variable types.

f7bf40ea6b refactor: optimize BIOS patching sequence with refined timing nomenclature 
Refined the BIOS patching and standardized
timing nomenclature for better technical clarity.

Changes:
- Ad technical documentation within the code.
- Standardized timing variables for better clarity:
    - BOOT_OFFSET: Replaces initial checkpoint.
    - FOLLOWUP_OFFSET: Replaces initial checkpoint2.
    - PULSE_COUNT: Replaces trigger .
    - BIT_OFFSET: Replaces hold .
    - OVERRIDE: Replaces patching.
