fix: plug memory map leak, save sp_el0, dynamic UART, kill loop
...
- Bootloader: reallocate memory map buffer when ExitBootServices fails,
so GetMemoryMap doesn't scribble past the old allocation on retry.
- vectors.S: actually store sp_el0 into the exception frame. Previously
it was read into x24 and then… vanished. EL0 tasks would wake up with
a corrupted stack pointer. Not great.
- Serial: split hardcoded 0x09000000 into a fallback default; add
SerialUpdate() so the DTB-parsed UART address actually gets used.
- DTB: add bounds check on reserved[] with PMM's 3 extra slots accounted
for, so malformed/overstuffed DTBs don't silently corrupt memory.
- PMM.h: bump kVMMaxReservedRegions 128→256, define kPMMReservedRegionCount.
- Types.h: remove `#define loop while(1)`. while(true) is fine.
- Rename IOSerial* → Serial* — the IO prefix was redundant, Serial.c
already lives under IO/.

- Add IOSerial: PL011 (0x0900_0000) TX with FIFO-full polling, yield while waiting
- Add Arch/IO.h (32-bit MMIO with DSB) and Arch/CPU.h (yield, WFI)
- Extend types.h (e.g. ASCII, Address, Int/UInt aliases)
- Wire KernelMain to IOSerialPutString for early boot output
- Drop .sourcekit-lsp config; note IO glob in CMake (commented)

Added bridging header for swift
...
c structures are now exposed to swift using a bridging header.
it is possible to access bootinfo using the structure (as oppossed to doing bytesfifts blind)
tested on aarch64 apple.
please test on other systems
