Eremey Valetov 5105ecafd6 Allow RND without parentheses, update Sphinx docs to v0.8.0
RND can now be called without parentheses (equivalent to RND(1)),
matching real GW-BASIC behavior for legacy code compatibility.

Update all Sphinx documentation pages to reflect features added in
v0.6.0-0.8.0: DATE$/TIME$/TIMER, FILES/SHELL/CHDIR/MKDIR/RMDIR,
AUTO/RENUM/DELETE, COMMON, LPRINT/LLIST with --lpt, --full TUI flag,
dynamic screen buffer, 54 tests.

Tests

54 test programs in tests/programs/. Run the full suite:

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.

Compatibility Testing

Compare output against real GWBASIC.EXE running under DOSBox-X:

# Generate .expected files from GWBASIC.EXE (requires DOSBox-X Flatpak)
bash tests/run_compat.sh --generate

# Compare gwbasic output against .expected
bash tests/run_compat.sh

CI

GitHub Actions runs on every push to main and on pull requests. The workflow builds the project with PulseAudio support and runs all 54 test programs.

See .github/workflows/ci.yml.
