v0.2.0: Neo Drift Out on the generic runtime, with sound and gamepads

Added

• Gamepads: the toolkit is pinned at neogeorecomp v0.2.0 (af96b2b), which reads up to two SDL2 gamepads as players 1 and 2 (neogeorecomp #6).
• Sound: the toolkit is pinned at neogeorecomp #3 (YM2610 synthesis through ymfm). The window plays it, --wav FILE writes it, --mute silences it. The build now enables C++ for ymfm, and setup.sh checks for g++. Sound is by @danilopaulinodasilva (neogeorecomp #3).
• CI: builds the interpreter-only player on Ubuntu, Windows and macOS on every push and PR.
• Installer (recomp-launcher): launcher/launcher.json and the installer workflow build Neo-Drift-Out-Installer for Windows, Linux and macOS on every push; a v* tag attaches them to the release.
• setup.sh runs on macOS (Homebrew), and both setup scripts print [n/N] steps for the installer's progress bar. On Windows, installing Git or CMake no longer stops setup for a rerun.

Changed

• Ported to the generic neogeorecomp runtime (neogeorecomp #1). The game boots through the real MVS BIOS and races on recompiled 68000 code; the repo holds only the ROM layout and test scripts.

Added

• neodrift_recomp generator (NEODRIFT_ROM_DIR), profile target, tests/coin_start.txt and tests/play_long.txt.
• Setup.cmd / setup.sh quick start, neogeorecomp as a submodule, toolkit.ref.
• README with Getting Started and screenshots; docs/game-notes.md.

Removed

• The hand-lifted routines, the generated src/autorecomp, the old Python generator, and the per-game runtime overrides (forced palettes, forced shrink, BIOS state pokes).
• ROM files, generated code and build output from the repository history (rewritten 2026-09-29).

Installers (Windows, Linux, macOS) are attached below once the installer workflow finishes. They hold no game data: pick the folder with your own MAME zips and they build the game on your machine. Built on neogeorecomp v0.2.0.
