Fix incompatibility issue with Boze

[sonhoang780]

Problem

Client crashes on startup when TrollHack runs alongside Boze:

InjectionError: Redirector applyCameraTransformationsMathHelperLerpProxy(FFF)F
in trollhack.mixins.json:render.MixinGameRenderer from mod trollhack failed
injection check, (0/1) succeeded. Scanned 0 target(s). No refMap loaded.

Root cause

MixinGameRenderer (targeting GameRenderer) had no explicit priority, so it
fell back to the config-level default (2100000000 in trollhack.mixins.json)
-- applied essentially last among all mixins. Boze's own loader transforms
GameRenderer.renderLevel earlier (lower/default priority), restructuring the
method before TrollHack's @Redirect scans it -- by the time it runs, the
literal Mth.lerp(FFF)F call site it targets no longer exists in that exact
form, so injection finds 0 targets and mixin throws. Verified via javap against
MC 26.1.2's real GameRenderer bytecode: the method + lerp call do exist
unmodified -- this isn't a wrong signature, it's an apply-order conflict.

Fix

• @Mixin(value = GameRenderer.class, priority = 500) -- apply before
  third-party mods with default/higher priority mutate the target method.
• require = 0 on the @Redirect as a safety net, so a similar conflict with
  some other mod degrades (feature silently no-ops) instead of crashing the
  whole client.

Testing

• :fabric:compileJava passes.
• Not yet retested live against Boze end-to-end (needs rebuild + relaunch).
