Subject: [PATCH] feat(app): add tile_cat_idx and buffers to App state

Add tile_cat_idx field to track selected tile category index.
Add buffers HashMap for named text buffers used in text-entry modes.

Update AppMode::TileSelect to remove nested cat_idx struct.
Update cmd_context to accept key and modifiers parameters.
Update cmd_context to populate new fields from App state.
