Major architectural refactorbto focus exclusively on JIT development.
JIT & Decoder Architecture
- Implemented scripts/generate_jit_decoder_a32_table.py to parse
instruction definitions at build-time rather than runtime.
- Moves decoder lookup tables from RAM to ROM.
Scope Reduction:
- Removed frontend, GUI, and rendering dependencies.
- delete src/frontend, src/target, and associated design docs.
Most importantly, this commit starts the transition of this codebase
from C++ to C. I cant stand creating C++ code, and since no one else
is contributing to this project this change shouldnt matter.

Rewrites the Arm32 instruction decoder to align with high integrity
software standards such as MISRA C and BARR-C.
Key Architectural Changes:
- Added compile time validation.
- Removed dependency on memory allocator. The decoder now uses
statically allocated global storage.
- Implement a hash-based lookup table to reduce decoding complexity to
O(1).
- Removed decoder_t in favour of a singleton pattern.
- Add documentation stating thread safety, preconditions, and
postconditions for all public functions.

Introduces the core Arm32 decoder, including the instruction parsing
mechanism and an initial set of defined instructions.
Signed-off-by: Ronald Caesar <github43132@proton.me>
Strengthens the decoder's foundation but does not yet implement the core
instruction lookup table logic or the public arm32_decode API. These
will be addressed in future patches.
