Wayland surface always reports current_extent as 0xFFFFFFFF (undefined),
meaning the swapchain size is determined by the application, not the
surface. Previous code returned early when this happened, so resize
never worked — cells stretched to fill the window.
Fix: when current_extent is 0xFFFFFFFF, use winit's window.inner_size()
to get the actual pixel dimensions. This works on both X11 and Wayland.
Both renderers (ascii + graphics) updated.

Both renderers (ascii + graphics) now support dynamic window resize:
- check_resize() called at start of every render() frame
- Compares surface capabilities with current swapchain extent
- If changed: recreates swapchain, image views, framebuffers, command buffers
- Recalculates grid_w/grid_h from new extent / cell_size (16x16)
- Reallocates instance buffer if grid cell count changed
- Old swapchain properly destroyed after new one created
- Handles window minimize (skip if extent = 0)
- physical_device field added back to both renderers (needed for surface caps query)
main.rs: vw/vh queried every frame from renderer.grid_w()/grid_h()
instead of cached once at startup. Camera center uses dynamic dimensions.
Result: resize window → more/fewer cells visible, cells stay 16x16 pixels.

Square cells:
- CHAR_W and CHAR_H both 16 (was 8x16, non-square)
- Window size updated to 160*16 x 50*16 = 2560x800
- Applies to both ascii and graphics renderers
Slope stepping collision:
- Before resolving X, check if new position overlaps solid
- If overlap, try stepping up 1 cell — if clear, snap up (walk up slope)
- If can't step up, resolve X normally (wall block)
- aabb_overlaps_solid() helper for fast overlap check
- Player can now walk up 1-cell-high steps and slopes

Three render modes:
- --mode terminal: pure ANSI ASCII in terminal
- --mode ascii: Vulkan window with ASCII characters (glyph atlas)
- --mode graphics: Vulkan window with colored cells (no glyphs, each
material = unique base color, no lighting yet)
Graphics renderer:
- Same Vulkan pipeline as ASCII but without glyph atlas
- Simpler shaders: graphics.vert/frag just output instance color
- No descriptor set, no texture sampling
- Each cell = colored quad, material color fills entire cell
- Entities rendered as colored shapes (player=yellow, goblin=green)
Default mode changed to --mode ascii
