Rewrite notes for the single-player architecture

Browse Source 
Drop protocol.md; rewrite the tick-loop note around the game-loop-driven sim
and the intent model; rewrite the roadmap (network items removed, sim/game
crate layout, save/load and NPC blocking added); fix crate paths in the
remaining notes.

# Map Loader
Loads level data from a Tiled CSV export, replacing the old hardcoded `build_world` wall loop.
Implemented in `server/src/map.rs`; wired into the world in `server/src/main.rs::load_world`.

The loader parses each field as `i64`, reinterprets the low 32 bits as `u32`, and strips the
flip flags with `& 0x1FFF_FFFF`, leaving the bare tile id. **Flip orientation is discarded for
now** — flipped tiles render unflipped. Real flipping would need a flip-aware `blit_tile` on
the client plus the flags carried through the protocol; deferred to the camera/sprite pass (09).

Tile ids are used directly:
- **Server** — `tile_flags(id)` (in `map.rs`) maps an id to gameplay `TileFlags`

order *is* the id space; keep the Tiled tileset and `overworld.tga` in lockstep.
No `firstgid` subtraction: the authored ids already line up with `overworld.tga`.
