Delete generate_snapshot from bridge/mod.rs — superseded by
perception::observer::compute_observer_snapshot. Not referenced
in any schedule or test.

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.

Implements ticket #341 for Sprint 3:
- Add DeserializationWithDump and MutexPoisoned variants to BridgeError
- Replace .expect("mutex poisoned") with graceful error propagation
in LocalBridge and TcpBridge (4 locations)
- Log first 256 bytes as hex dump on deserialization failure for
debugging malformed payloads
- Classify errors in receive_bridge_inputs: BrokenPipe/ConnectionReset
→ clean shutdown, MutexPoisoned → shutdown, DeserializationWithDump
→ skip frame (recoverable)

- 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.

Perception system emits DirectObservation/LeftLOS knowledge events
based on snapshot visibility. Entities entering LOS get Direct
confidence; leaving LOS downgrades to KnowsDetails. System params
are optional for backward compatibility when KnowledgePlugin is not
registered. 28 knowledge graph unit tests included.

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.

Replace string-matching disconnect detection with explicit
BridgeError::Disconnected variant. Add TcpBridge::accept_on(listener)
that takes a pre-bound TcpListener, eliminating the 100ms sleep hack
in TCP tests. Send errors now also trigger ServerRunning=false.
Add trace logging to generate_snapshot for entity count visibility.

Implements the full server-side tick pipeline:
- process_player_input drains InputQueue, converts PlayerActions to
MoveIntent components or pause/unpause toggles
- generate_snapshot builds ObserverSnapshot from ECS state with
render coordinate conversion
- receive_bridge_inputs/send_bridge_snapshot handle bridge I/O with
graceful disconnect detection via ServerRunning resource
- main.rs now accepts TCP connections and runs a proper game loop
- PlayerCharacter marker, Player EntityKind, SnapshotBuffer resource
Closes server side of #81, #82, #83.

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.
