Implement binary SAVE/LOAD, INKEY$ extended keys, golden tests, update to v0.10.0

Browse Source 
Binary SAVE/LOAD: SAVE now writes tokenized binary by default (0xFF header
format), matching original GW-BASIC behavior. SAVE "file",A for ASCII.
LOAD auto-detects binary vs ASCII from the first byte. Command-line file
loading also auto-detects, so binary .BAS files just work.

INKEY$ extended keys: arrow keys, Home/End/PgUp/PgDn, Insert/Delete, and
F1-F10 now return the correct CHR$(0) + scan_code two-byte sequences per
the IBM PC convention. Refactored event trap key parsing to use tui_read_key()
instead of duplicating escape sequence parsing.

Golden-file regression tests: generated .expected output files for 55 of 58
test programs (3 timing-dependent tests excluded). The test runner now
reports compat match status alongside pass/fail.

Classic programs: added Hamurabi, Lunar Lander, Gunner, and Diamond from
David Ahl's BASIC Computer Games (1978) in tests/classic/ for manual
compatibility testing.

Docs updated with compiler roadmap item and hardware I/O simulator plan.

## Tests
56 test programs in `tests/programs/`. Run the full suite:
58 test programs in `tests/programs/`, plus 4 classic interactive programs in
`tests/classic/` (Hamurabi, Lunar Lander, Gunner, Diamond from David Ahl's
*BASIC Computer Games*).
Run the full automated suite:
```bash
bash tests/run_tests.sh
```
Each test has a 5-second timeout. When `.expected` files are present
(generated from real GWBASIC.EXE), the runner also reports compatibility
match status.
Each test has a 5-second timeout. 55 tests have `.expected` golden files
for output regression detection. Three timing-dependent tests (datetime,
on_timer, timer_stop) run without golden comparison.

## CI
GitHub Actions runs on every push to `main` and on pull requests. The workflow
builds the project with PulseAudio support and runs all 56 test programs.
