refactor: chunk load (#21)

Browse Source 
* feat(renderer): add fog effect based on render distance

* refactor(gameplay): remove dead code and simplify chunk neighbor context

Remove the large commented-out `init_chunks()` function, and eliminate the `affected_neighbor` tracking in `gen_chunks_internal()`. This simplifies the neighbor context building and removes unused vertex data regeneration for affected neighbors.

* refactor(gameplay): move chunk generation phases into gen_chunk method

Consolidate multiple phase generation calls into a single gen_chunk() method on Chunk, which handles neighbor generation and ensures thread safety. Simplify World::gen_chunks_internal by using gen_chunk() instead of manual phase orchestration.

* fix(gameplay): use gen_phase_one to get seed

* feat(world): integrate thread pool and async chunk generation

* fix(renderer): correct shader uniform name and remove unused uniform

* feat(gameplay): add temporary chunk flag to prevent path clearing

* fix: add thread safety for cave and river path mutexes

* refactor: remove unused uniforms and set cameraPos uniform outside lambda

* feat(world): add dynamic thread pool resizing

* feat(world): add thread pool size management and UI controls

* feat(world): add ChunkLoadStyle enum and rename chunk_pos to get_chunk_pos

* feat(player): add configurable fly Y speed

* refactor(world): add thread pool start/stop and auto-detect threads

Extract thread pool starting and stopping into dedicated methods. Set default pool threads to 0 to enable automatic detection of available cores, and ensure thread pool is properly managed during world rebuild.

* fix: include shared_mutex header

* fix(gameplay): simplify set_chunk_load_style switch and fix fallthrough bug

* fix(world): add missing include for <utility>
