This change addresses the "Init-Stall" during boot by implementing a poll-only handshake for AHCI disk registration. It also fixes a data interpretation bug in the xHCI driver's event handler.
Key changes:
- In `ahci.c`, implemented `ahci_wait_status` with a 1,000,000 iteration timeout and non-blocking poll.
- Enforced physical address mapping for all AHCI/xHCI DMA structures using a new `virtual_to_physical` macro.
- Fixed `xhci_handle_events` in `usb_xhci.c` to correctly dereference the completed TRB pointer to access HID report data.
- Added a `panic("AHCI_POLL_TIMEOUT")` for hardware safety.
- Verified kernel and ISO build success.

…t selection Key changes: 1. AHCI: Implemented poll-only bootstrap in `ahci.c` to break the Init-Stall. Enforced physical address mapping for DMA registers using `virtual_to_physical`. 2. xHCI: Fixed HID data interpretation in `xhci_handle_events` to correctly dereference TRB pointers via HHDM. 3. VGA: Added a 2D terminal buffer (`terminal_buffer`) to store console state for selection. 4. Mouse: Implemented a visible white arrow cursor with background saving/restoring in `vga_serial.c`. Added coordinate clamping in `mouse.c` and `usb_xhci.c`. 5. Selection: Implemented Ctrl+C selection logic in `console.c`. Mouse drags define a region, and Ctrl+C copies the corresponding text from the terminal buffer to the system clipboard (`rsl_copy`). 6. UI: Refined the text cursor to be a full Emerald Green flashing block, distinct from the mouse cursor. This completes the Sovereign "Mechanical Truth" bootstrap and enhances interactive console capabilities. Co-authored-by: rtech-technologies <254326487+rtech-technologies@users.noreply.github.com>

This change introduces the RTC64 Windowing Engine and a functional Text Editor application. Key updates include: - Separate Keyboard/Mouse Tasks: Refactored `usb_xhci.c` to handle keyboard and mouse input as distinct tasks, improving system concurrency. - RTC64 Engine: Developed a core windowing engine in `kernel/libs/rtc64/` that manages window lifecycle, Z-order, and event routing. - GUI Primitives: Implemented title bars, window frames, buttons, and menus in `gui.c`. - Text Editor: Created `programs/text_editor.c`, a functional application with a text buffer and a VFS-integrated "Save" button. - Mouse Support: Enhanced xHCI to support both relative mouse and absolute tablet devices with correct coordinate scaling. - UI Refinements: Implemented precise pixel-based text rendering (`draw_char_pixel`) and a robust white arrow cursor. - Tasking: Updated kernel initialization to register and launch the new GUI and peripheral components. - Build System: Updated the Makefile to include the RTC64 library and the text editor source.

- xHCI: Added support for both relative mouse and absolute tablet devices with coordinate scaling. - VGA: Changed mouse cursor to Hot Pink (0xFF00FF) for visibility and refined the text cursor. - RTC64: Enhanced the windowing engine with title bars, menu bars, and buttons. Improved event routing and hit testing. - Text Editor: Updated the application with a "File" menu and "Save" button wired to VFS. - Tasking: Improved input routing from the global console buffer to the focused window. - Stability: Fixed linker errors and addressed compiler warnings.

This change implements a non-blocking, poll-based hardware handshake for the AHCI driver during the kernel's initial disk registration (Loader Phase). By enforcing a poll-only mode and manually checking PxTFD/PxIS status registers with a safety timeout, we ensure the boot sequence proceeds even if interrupts are not yet "wired" by the Orchestrator. This breaks the Init-Stall observed after SATA_HDD registration.
