Implement compute_nearby_interactions system that detects entities
within close (≤2) and mid (≤5) Manhattan distance, computes
available verbs per D-060 spec. NPCs get Talk+Observe at close
range, Observe-only at mid range; PersonOfInterest flips priority.
Objects get Examine. Results populate nearby_interactions[] on
ObserverSnapshot v4. Bump protocol version 3→4. Implements #404.

- Filter remembered entities by z-level (Hoshe + Tyre warning)
- Skip remembered ghosts on currently visible tiles (Hoshe warning)
- Bump ObserverSnapshot version to 3 (Tyre suggestion)
- Add edge case tests: visible tile collision, different z-level,
knowledge without position (Hoshe suggestion)
- Regenerate msgpack fixtures for v3

VisibleEntity now carries relationship state (D-033 entity color) and
observation type (Visible vs Remembered). compute_observer_snapshot
queries the player's KnowledgeGraph to overlay relationship data on
visible entities and include remembered (not-in-LOS) entities as fog
ghosts at their last known position. Regenerated msgpack fixtures.

Replace unfiltered generate_snapshot with compute_observer_snapshot
that combines shadowcasting + vision cone to send only visible
entities and tiles. Enforces information asymmetry (D-011): NPCs
behind walls or in the blind spot are excluded from the snapshot.

Client-side Protocol.gd expects rmp_serde::to_vec_named() (maps with
string keys), but LocalBridge was using to_vec() (compact positional
arrays). Fix send_snapshot and update all test serialization calls to
match actual wire format. Also change EOF from Ok(vec![]) to
BridgeError::Transport so bridge systems can detect disconnects.

Length-prefixed MessagePack framing (4-byte BE length + payload),
LocalBridge struct implementing SimBridge trait over Unix domain
sockets, BridgeResource wrapper for ECS integration. Adds Io
error variant to BridgeError. Two integration tests verify
snapshot and input round-trips over real sockets.
