Release v0.16.0: AOT compiler (89%), Jupyter kernel, Hardware I/O, string GC

Browse Source 
Version 0.16.0 consolidates the major features added since v0.14.0:

Ahead-of-time compiler (gwbasic-compile):
  - Translates .bas programs to C source → GCC → native executables
  - 64 of 72 test programs produce correct output (89%)
  - Zero compile errors — all 72 programs compile successfully
  - Token embedding for complex statements (PRINT USING, DEF FN,
    graphics, file I/O, MID$ assignment)
  - String comparison, division-by-zero detection, ON ERROR GOTO/RESUME
  - libgwrt.a runtime library from existing interpreter modules

Jupyter kernel (gwbasickernel):
  - Persistent subprocess with sentinel protocol
  - Inline Sixel graphics rendering (pure-Python decoder → PNG)
  - INPUT statement support via Jupyter stdin protocol
  - Pygments GW-BASIC syntax highlighter

Hardware I/O simulator (portio.c):
  - 8253 PIT, PPI speaker, CGA mode/color, COM1, game port
  - Continuous tone via PulseAudio pthread worker

Interpreter improvements:
  - 100% token coverage (all 144 GW-BASIC tokens handled)
  - String space pool with compacting garbage collector
  - RESET, ENVIRON/ENVIRON$, ERDEV/ERDEV$, IOCTL/IOCTL$,
    LCOPY, DATE$/TIME$ assignment, CALL, COM
