Introduces the first unit tests for the ARM32 JIT decoder. A new script
automatically generates a test case for every instruction in arm32.inc,
providing 100% of the isa.
This also includes a critical rework of the decoder's lookup table
generation logic. The previous hashing method was flawed, causing
build-time overflows and incorrect instruction matching (shadowing) for
patterns with wildcards. The new algorithm correctly populates the
lookup table.

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.
