- Updated memory management in `memory.zig` to improve virtual buffer allocation and deallocation.
- Removed `sensei.zig` and refactored scheduling logic into new files: `queue.zig`, `sensei.zig`, and `waker.zig`.
- Introduced `attachment.zig` for managing attachments with new constants and limits.
- Created `pool.zig` for managing the Kata pool, including creation and dissolution of Katas.
- Enhanced `types.zig` to define new structures and enums for Katas and their states.
- Improved context switching in `shift.zig` to streamline Kata execution state management.
- Updated file references and imports across the codebase to reflect new structure.

- Renamed panic.zig to crimson.zig for clarity and restructured panic handling functions.
- Moved exception handling logic from exceptions.zig to a new exception.zig file.
- Updated imports across the codebase to reflect the new file structure.
- Introduced a new types.zig file to define Context and ExceptionFrame structures.
- Added formatting utilities in format.zig for better register and stack frame representation.
- Implemented screen rendering functions in render.zig for displaying error messages and system state during panic.
- Consolidated color definitions in colors.zig and added new constants for better readability.
- Removed obsolete exception handling code and integrated it into the new structure.

- Renamed I/O port functions for clarity: `write_port_byte` to `out_byte`, `read_port_byte` to `in_byte`, `write_port_word` to `out_word`, `read_port_word` to `in_word`, `write_port_long` to `out_long`, and `read_port_long` to `in_long`.
- Updated import paths for serial, ahci, ata, gpt, keyboard, terminal, and other drivers to reflect new directory structure.
- Replaced instances of `read_file_by_path` with `view_unit_at` in various files for consistency.
- Added new utility functions for AHCI FIS setup and defined types for AHCI and PCI.
- Introduced string copy utilities for handling strings from Kata pointers.

- Moved ISR and IRQ handler definitions to a new assembly file (isr.zig).
- Simplified IDT setup by using ISR and IRQ handlers from isr.zig.
- Replaced inline assembly for IRQ handlers with calls to new ISR functions.
- Introduced a new context switching mechanism in context.zig for Kata execution.
- Updated syscall entry handling in entry.zig to streamline context saving and restoring.
- Removed redundant context structures and functions from shift.zig.
- Improved clarity and organization of syscall and interrupt handling code.
