Endless v0.10.1

Endless 0.10.1

• Capture immutable sparse block palettes in a bounded camera vicinity once per vanilla render chunk on Minecraft 1.20.1 and 1.21.1, avoiding synchronized world lookups for each meshing block read. Preserve live block-entity discovery, distant-query fallback and normal rebuild invalidation.
• Add a production-client FPS comparison against vanilla, Fabric alone, and Endless 0.10, with frame-time tails, native framebuffer checks, and local-only raw results.

What's Changed

• Fix per-workload benchmark execution validation by @UpperMoon0 in #29
• perf: optimize sparse client meshing and benchmark FPS (0.10.1) by @UpperMoon0 in #28
