why?
- we need to format it externally too.
- a in-kernel format doesn't handle every case.
- and i have to fix the createdir, createfile methods for correct inode dir linking.

why?
- HeFS's Formating needs some thought before being layed out, that's the kind of thing that bites hard in the ass.
- Alongside those changes I improved parts of the kernel too.

Details:
- Added support for 512 process teams (kTeams array).
- New SwitchTeam() API in UserProcessScheduler.
- Kernel main loop rotates active team every 200ms.
- Renamed syscall tables for clarity (kSyscalls → kSysCalls, etc.).
- Replaced kKernelMaxSystemCalls with kMaxDispatchCallCount.
- Updated call sites to match new naming.
- Bumped format version to 0x0101.
- Added reserved fields to HEFS_BOOT_NODE for future use.
- Changed inode indexing logic to operate on (start, size) pairs.

Renamed `fDriveKind` to `fProtocol` across kernel storage subsystems
to clarify its purpose as a protocol identifier (e.g., "AHCI", "ATA-")
rather than a general "kind" classification.
Updated all affected header and source files:
- DriveMgr, HeFS, AHCI, ATADeviceInterface, and NeFS now consistently
reference `fProtocol()` instead of `fDriveKind()`.
- Added streaming operators (`<<`, `>>`) to AHCI and ATA device
interfaces for improved mountpoint interaction.
- Promoted `GetPortsImplemented()` and `SetPortsImplemented()` to
public for AHCI device configuration.
- Added null checks and protocol verification logic in stream operators.
This refactor improves clarity and consistency when working with
storage devices across the kernel.

This patch begins a major cleanup and enhancement of AHCI I/O handling:
- Refactored AHCI command setup logic to prepare FIS and PRDT entries more correctly.
- Fixed miscalculation of 48-bit LBA extraction from IDENTIFY response.
- Rewrote PRDT loop to increment physical address per entry instead of recomputing offsets.
- Replaced read/write/identify branching with unified ternary logic for clarity.
- Ensured proper stopping and reinitialization of command engine before issuing commands.
- Explicitly remap and zero command list base, FIS base, and command table areas.
- Made command slot lookup more robust.
- Added fallback wait after command completion to avoid SRBSY/SRDRQ residue.
- Dropped misused `YES` flag in read/write call sites — now passed only when needed.
Also includes:
- Minor cleanup in `BootKit.h` (whitespace).
- NeFS debug message clarified to avoid accidental fork overwrites.
This is a **work-in-progress** rework of the AHCI path. Next steps will involve:
- More robust error recovery.
- Support for non-512 sector drives.
- Support for multiple ports and NCQ.
