fix: window input uses get_keys() for held state, glyph atlas for FPS

Browse Source 
Input fix: get_keys_pressed(No) only fires on initial press, not held.
Switched to get_keys() which returns all currently-down keys every frame.
Jump still edge-triggered via jump_was_down flag.

Performance fix: pre-build glyph atlas at startup (all ASCII chars
rasterized once into 128x256 alpha bitmap). No per-frame cloning.
draw_cell reads atlas alpha + blends fg/bg inline. Zero allocations
in render loop.
