Replace legacy DrawXxxCmd structs with RenderMessage variants for all
10 Rust-produced command types. Variable-length commands (LineStrip,
Polygon) use alloc_aux() for vertex data with explicit pointers in the
enum, avoiding layout coupling. Remove legacy structs and command_type
constants module.

refactor: propagate types and trim comments in render hook shims
Replace u32 params with Fixed, SpriteOp, and typed pointers across
render_queue.rs and display_vtable.rs. Propagate to core callees
(blit_sprite, bungee_trail, crosshair_line). Trim comments to just
Ghidra name + address.
