feat: integrate Wasuro WASM runtime into Asuro build chain

- Add compile_wasuro.sh to sparse-clone Wasuro src/wasm from gitea
  (develop branch) with caching to skip redundant pulls
- Update compile.sh to include wasuro build step in pipeline
- Update compile_sources.sh to dynamically discover -Fu paths via
  find across src/ and wasuro/ directories
- Extend system.pas with FPC 3.2.2 compilerprocs required by Wasuro:
  - 64-bit signed/unsigned div and mod (fpc_div_int64, fpc_mod_int64,
    fpc_div_qword, fpc_mod_qword) with correct i386 parameter mapping
  - 64-bit multiply (fpc_mul_int64) via three 32-bit MUL instructions
  - Float-to-integer intrinsics (Trunc, Round) using x87 FPU
  - Memory allocation compilerprocs (fpc_getmem, fpc_freemem)
    delegating to kernel kalloc/kfree
  - Exception handling stubs (reraise, raiseexception, catches, doneexception)
  - setjmp/longjmp for exception address stack
  - Fix sInt64 type alias (was longint/32-bit, now int64/64-bit)
  - Add serial debug helpers (COM1 $3F8) for bare-metal tracing
- Wire up Wasuro in kernel.pas: init WASM VM, set I/O callback to
  syslog, and run all 1103 Wasuro tests (0 failures)
- Update .gitignore to exclude wasuro/ cache directory
