Hei Prism 1.0.0-beta.1 — RELEASE CANDIDATE AUDIT

Stability fixes:
- Rebuilt the internal i18n fallback so broken strings such as Configura??es / Dist?ncia / N?o cannot leak into the GUI if a locale resource fails to resolve.
- Kept all 25 locale packs synchronized with the same 119 UI keys and UTF-8 decoding.
- Disabled the obsolete hidden manual shader-engine click handler; shader compatibility remains automatic.
- Preserved immediate shader apply behavior and clear states for no shaderpacks / unrecognized shaderpacks / apply failures.
- Cleaned dynamic shader labels so Optional[...] and obsolete Vitrail branding do not leak into pack labels.
- Removed dead HpShaderToggleLegacy bytecode.
- Corrected runtime version/log reporting to 1.0.0-beta.1.
- Kept the startup recovery path: bootstrap and FPS initialization are isolated so one recoverable subsystem failure does not intentionally terminate the client.

Mixin policy for Beta:
- Only GuiScreenRouterMixin, FramerateLimitTrackerMixin and ExtendedFpsLimiterMixin remain.
- The Hei Prism mixin config is non-required and uses defaultRequire=0.
- Debug/logo cleanup mixins that previously caused startup regressions are absent.
- Embedded Iris, Sodium and ImmediatelyFast JARs are not modified by this Beta build.
