The benchmark API captures per-frame data from the game loop, which is
bypassed when using step()-based simulation control. This warning
informs users to use Python's time module for headless performance
measurement instead.
Also adds test_headless_benchmark.py which verifies:
- step() and screenshot() don't produce benchmark frames
- Wall-clock timing for headless operations
- Complex scene throughput measurement

Implements Python-controlled simulation advancement for headless mode:
- Add mcrfpy.step(dt) to advance simulation by dt seconds
- step(None) advances to next scheduled event (timer/animation)
- Timers use simulation_time in headless mode for deterministic behavior
- automation.screenshot() now renders synchronously in headless mode
(captures current state, not previous frame)
This enables LLM agent orchestration (#156) by allowing:
- Set perspective, take screenshot, query LLM - all synchronous
- Deterministic simulation control without frame timing issues
- Event-driven advancement with step(None)

GridPoint.entities (#114):
- Returns list of entities at this grid cell position
- Enables convenient cell-based entity queries without manual iteration
- Example: grid.at(5, 5).entities → [<Entity>, <Entity>]
GridPointState.point (#16):
- Returns GridPoint if entity has discovered this cell, None otherwise
- Respects entity's perspective: undiscovered cells return None
- Enables entity.at(x,y).point.walkable style access
- Live reference: changes to GridPoint are immediately visible
This provides a simpler solution for #16 without the complexity of
caching stale GridPoint copies. The visible/discovered flags indicate
whether the entity "should" trust the data; Python can implement
memory systems if needed.

Adds a sub-grid system where grids larger than 64x64 cells are automatically
divided into 64x64 chunks, each with its own RenderTexture for incremental
rendering. This significantly improves performance for large grids by:
- Only re-rendering dirty chunks when cells are modified
- Caching rendered chunk textures between frames
- Viewport culling at the chunk level (skip invisible chunks entirely)
Implementation details:
- GridChunk class manages individual 64x64 cell regions with dirty tracking
- ChunkManager organizes chunks and routes cell access appropriately
- UIGrid::at() method transparently routes through chunks for large grids
- UIGrid::render() uses chunk-based blitting for large grids
- Compile-time CHUNK_SIZE (64) and CHUNK_THRESHOLD (64) constants
- Small grids (<= 64x64) continue to use flat storage (no regression)
Benchmark results show ~2x improvement in base layer render time for 100x100
grids (0.45ms -> 0.22ms) due to chunk caching.
Note: Dynamic layers (#147) still use full-grid textures; extending chunk
system to layers is tracked separately as #150.

Implement per-layer dirty tracking and RenderTexture caching for
ColorLayer and TileLayer. Each layer now maintains its own cached
texture and only re-renders when content changes.
Key changes:
- Add dirty flag, cached_texture, and cached_sprite to GridLayer base
- Implement renderToTexture() for both ColorLayer and TileLayer
- Mark layers dirty on: set(), fill(), resize(), texture change
- Viewport changes (center/zoom) just blit cached texture portion
- Fallback to direct rendering if texture creation fails
- Add regression test with performance benchmarks
Expected performance improvement: Static layers render once, then
viewport panning/zooming only requires texture blitting instead of
re-rendering all cells.

Implements ColorLayer and TileLayer classes with z_index ordering:
- ColorLayer: stores RGBA color per cell for overlays, fog of war, etc.
- TileLayer: stores sprite index per cell with optional texture
- z_index < 0: renders below entities
- z_index >= 0: renders above entities
Python API:
- grid.add_layer(type, z_index, texture) - create layer
- grid.remove_layer(layer) - remove layer
- grid.layers - list of layers sorted by z_index
- grid.layer(z_index) - get layer by z_index
- layer.at(x,y) / layer.set(x,y,value) - cell access
- layer.fill(value) - fill entire layer
Layers are allocated separately from UIGridPoint, reducing memory
for grids that don't need all features. Base grid retains walkable/
transparent arrays for TCOD pathfinding.

compute_fov() was iterating through the entire grid to build a Python
list of visible cells, causing O(grid_size) performance instead of
O(radius²). On a 1000×1000 grid this was 15.76ms vs 0.48ms.
The fix returns None instead - users should use is_in_fov() to query
visibility, which is the pattern already used by existing code.
Performance: 33x speedup (15.76ms → 0.48ms on 1M cell grid)

Track actual work time separately from frame time to determine
system load percentage:
- work_time_ms: Time spent doing actual work before display()
- sleep_time = frame_time_ms - work_time_ms

load% = (work_time / frame_time) * 100

Breaking change: UICollection.remove() now takes a value (element) instead
of an index, matching Python's list.remove() behavior.
New methods added to both UICollection and EntityCollection:
- pop([index]) -> element: Remove and return element at index (default: last)
- insert(index, element): Insert element at position
Semantic fixes:
- remove(element): Now removes first occurrence of element (was: remove by index)
- All methods now have docstrings documenting behavior
Note on z_index sorting: The collections are sorted by z_index before each
render. Using index-based operations (pop, insert) with non-default z_index
values may produce unexpected results. Use name-based .find() for stable
element access when z_index sorting is in use.
