* feat(gameplay): add time sync and network improvements
* fix: correct neighbor block indexing and add time update support
* feat(gameplay): optimize chunk request with player chunk tracking
Add `update_player_chunk()` method to `ClientPlayer` that triggers a chunk request when the player moves more than 2 chunks away from the last recorded chunk.

* refactor(gameplay): rename remote player types and add interpolation
* refactor(server_world): use thread pool for chunk request handling
* refactor(packet): replace if-constexpr chain with explicit template specializations
Refactor `get_packet_id()` by removing the if-constexpr chain and instead
providing explicit specializations for each packet type. This simplifies the
primary template (which now only contains a static assertion) and improves
compile-time dispatch clarity. The `always_false` helper is no longer needed
in the primary template.
* feat(gameplay): add packet to clear all chunks on server rebuild
Add new packet S2C_ClearAllChunks (ID 3005) to notify clients when the server rebuilds its world. Clients respond by clearing their chunk cache and requesting fresh chunks. Shift UPDATE_TIME packet ID to 3006 to accommodate.

Introduce a second thread pool for network operations and a `ThreadPoolKind` enum to distinguish between gen and net pools. Rename `pool_threads()` to `gen_pool_threads()`, add `change_pool_threads()` overload that accepts the pool kind, and update the dev panel to use the gen pool. Adjust logging and initialization to handle both pools.
* feat(client_world): implement server exit acknowledgment with timeout
* feat(gameplay): implement server stop and client exit handling
Add server_stop flag to LogoutRsp protocol. Modify client_world to check for server stop or own logout to set exit flag. Add ServerWorld::stop() to broadcast stop and cleanly shut down. Refactor chunk ownership to unique_ptr. Remove name parameter from get_look_block_pos.
* fix(app): correct port validation and remove redundant TOML helper
* fix: address unused parameter warnings and missing port assignment

* refactor(gameplay): migrate chunk storage to tbb::concurrent_hash_map
* refactor(server_world): replace future-based chunk generation with queue
Remove `std::future` per-chunk tracking and poll_finished_chunks().
Instead, generation tasks push completed chunks to a concurrent queue
consumed during update. This eliminates wait_all_chunk_tasks() and
simplifies synchronization.
* refactor(client_world): use concurrent data structures for chunk management
Replace std::shared_mutex and std::unordered_set with tbb::concurrent_hash_map for chunk storage, tbb::concurrent_queue for pending uploads, and absl::flat_hash_set for player chunk positions. This improves thread safety and reduces locking overhead. Refactor receive_chunk and request_chunk to work with the new concurrent model.
* build(windows): add Nvidia and AMD GPU high performance exports
* fix(ci): update header file pattern in clang-format check

In texture management, rename `m_pbr_texture_array` to `m_normal_texture_array` to reflect its actual usage, and set texture wrap mode to `GL_REPEAT` for both the block and normal texture arrays.
* fix(primitive_data): correct back face texture coordinates and tangents
* fix(texture-manager): correct texture deletion and refactor reload
Make hot_reload private and add public need_reload method. Update UI to call need_reload instead of hot_reload. Fix incorrect use of glDeleteBuffers for normal texture array by using glDeleteTextures.
* refactor(chunk): add ChunkInfo and switch to shared_mutex for chunk access
Introduced ChunkInfo struct to expose chunk metadata (position, seed, biome). Replaced std::mutex with std::shared_mutex for chunk map to allow concurrent read access. Added World::get_chunk_info() method. Temporarily disabled cave/river cleanup and debug biome reporting.
* refactor(cave,river,chunk): use ChunkPos as key for paths and track cave existence
* refactor(gameplay): use deterministic origin-based cave and river generation
Compute cave and river paths on-the-fly per chunk from a deterministic origin instead of storing them globally. Remove concurrent hash map storage, shared mutexes, and related cleanup methods. This simplifies concurrency and reduces memory overhead.
* refactor(world): remove unused chunk generation progress tracking
* 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.

* feat(renderer): make ambient strength adjustable via dev panel
* fix(game_time): use unsigned tick type and enforce positive tick speed
* feat(renderer): add shadow mapping with PCF soft shadows
Introduce shadow mapping using a dedicated depth framebuffer and shader. The block fragment shader now performs percentage-closer filtering (PCF) with Poisson disk sampling and random rotation for soft shadows. The vertex shader outputs light-space coordinates. A new depth shader pair handles rendering from the light's perspective, discarding transparent fragments. The renderer sets up the light projection based on the camera position and sun direction, and applies the shadow factor to diffuse lighting. Day/night cycle can now be toggled off in the world server thread.

* refactor(gameplay): replace VBO with VAO for vertex data
* fix(renderer): move depth test enable to world rendering
The `glEnable(GL_DEPTH_TEST)` call was incorrectly placed in the general `render()` function, affecting UI and text rendering. Moved it to the start of the world rendering loop to ensure depth testing is only active during 3D world pass.
