gen2recomp: initial commit

A native LOVE2D recreation of Pokemon Gold and Silver, built on
Gen1Recomp's Red/Blue/Yellow engine. Game data and graphics are decoded
at runtime from a ROM the player supplies; none is distributed here.

History starts fresh so that no ROM-derived or third-party binary
content is carried in past commits. Excluded and now gitignored:

- mods/example_mew_starter/assets/: inverted Mew battle sprites that
  tools/generate_example_mod_sprite.py derives from an imported cache.
  mod.card already documented assets/ as empty until that script runs.
- ruins_kabuto: an in-game screenshot of the Ruins of Alph rendering
  ROM-derived tiles and sprites.
- tools/vendor/: pret symbol files and prebuilt RGBDS binaries, which
  scripts/setup_gen2_symbols.ps1 fetches on demand.
