Subject: [PATCH] feat(command): add CmdContext extensions and new effects

Add new fields to CmdContext for tracking search mode, panel cursors,
tile category index, named text buffers, and key information.

Add SetBuffer and SetTileCatIdx effects for managing application state.
Update TileBar to accept tile_cat_idx parameter for rendering.
