feat: v2 — queue matchmaking, procedural audio, sprite archetypes, auth

- Add queue-based matchmaking with Elo-proximity and 10s timeout
- Procedural sound engine (SFX, voice announcer, 4-track music)
- Sprite system refactored into 6 archetypes (standard, lobster, sheep, cyborg, blob, tank)
- 42+ fight choreographies with themed/generic/wild card selection
- 4 KO finish styles, super-speed mode, hyperdetail close-ups
- Auth routes, JoinBout page, bot profile with stats
- 7-tier ranking system (Baby through Legend)
- Arena and challenge system expansions
