This PR hardens the system boot sequence by enforcing strict hardware synchronization and state validation, as per the Quartermaster's mission.

Key changes:

  • AHCI Driver: Added BIOS/OS Handoff (BOHC) and refined GHC reset logic to ensure deterministic controller state.
  • Port Initialization: Refactored port setup into a unified function with rigorous polling of the SSTS (SATA Status) and TFD (Task File Data) registers during COMRESET.
  • Payload Validation: Added sanity checks for Limine modules (RAMDISK) to ensure valid memory addresses and non-zero sizes before registration.
  • Logistics Logging: Introduced '⚓' markers in the boot log to signify verified hardware handshakes.
  • Audit Trail: Created boot_manifest.md to document the synchronization status of critical boot stages.

⚓ Quartermaster: Hardened AHCI Handshake and Payload Validation
225b1b5 
- Implemented BIOS/OS Handoff (BOHC) in AHCI driver.
- Hardened GHC reset sequence with verified AE/HR bit stability.
- Unified port initialization into `ahci_init_port`.
- Strengthened `ahci_force_port_reset` with engine-stop verification and COMRESET DET-bit state machine.
- Added explicit payload validation for Limine ramdisk module.
- Enhanced boot logs with ⚓ logistics markers.
- Added `boot_manifest.md` for synchronization analysis.
