feat: promote and refine performance settings

[Slush97]

Summary

• normalize and center Locker General empty states
• promote Performance configs from experimental Game Setup into permanent Settings
• simplify the Performance card hierarchy and remove duplicate copy
• fix Sqooky artist links returning an empty Mods view
• show release versions in Sqooky version history and match bundled releases by path-scoped commit identity

Review fixes

• preserve hidden-creator filtering for normal artist pages while allowing only the explicit Performance credit navigation
• derive each bundled prose release path commit during preset generation, avoiding title guesses and unnecessary history fetches
• add regression coverage for Browse artist overrides and bundled history matching

Validation

• ESLint
• pnpm typecheck
• pnpm i18n:check
• pnpm perf:presets --check
• full Vitest suite (1,297 tests passed)
• production build with GRIMOIRE_SOCIAL_BASE_URL configured
