Documents the \`enum Name { Variant, ... }\` syntax and adds
\`--dump-ir\` and \`--use-ast\` to the CLI flag table. Also adds
an integration test covering enum-variant-as-condition and variant
assignment through the full compile pipeline.

The IR-based codegen now matches all features of the AST codegen
(state dispatch, multi-OAM, P1/P2 input, scroll, debug.log/assert),
so flip the default. The legacy AST codegen is still available via
--use-ast for comparison and fallback during validation.

resolve_sprites() now handles all three AssetSource variants:
- Inline(bytes): use directly (existing behavior)
- Binary(path): read raw bytes from file relative to source_dir
- Chr(path): convert PNG to CHR via png_to_chr()
Missing files are silently skipped rather than erroring, so
declarations can reference assets that haven't been added yet.
This keeps existing tests that use placeholder file paths working.
Updated future-work.md: moved include directive, P2 controller,
sprite resolution, shift-assign, debug statements, warnings, and
asset wiring to the "completed" section. Remaining work is IR codegen,
audio, on_scanline, and language features (structs/enums).
Tests: 257 total (3 new resolve_sprites tests)
