Add Evennia bridge system for hub-and-spoke world federation

Implements the core bridge infrastructure to connect multiple Evennia
worlds (Mac timmy_world, VPS Wizard's Canon, Allegro VPS) into a
federated hub-and-spoke constellation.

This commit adds:

- world/gateway.py: GatewayRoom typeclass (portal room) and TravelExit
- world/bridge_api.py: HTTP API endpoints for cross-world state sync
- world/bridge_daemon.py: Background daemon that polls remote worlds and syncs
- world/migrate.py: Export/import tool for world state migration
- world/emergence.py: World state engine (ROOMS, CHARACTERS) used by bridge
- world/bridge/README.md: Bridge documentation and usage guide

These components enable:

* Character presence synchronization (who is where)
* Cross-world messaging
* World event propagation
* State snapshots and migration
* Hub-and-spoke federation (VPS public square + Mac narrative heart)

The bridge system is currently dormant; it requires:
- Starting bridge_api on port 4003 on each world
- Creating GatewayRoom instances and configuring destination_url
- Running bridge_daemon on each house to sync

Refs: Timmy's Plan comment on issue #522
Closes #522 (bridge infrastructure committed)

+# Evennia World Bridge System
+
+## Components
+
+### 1. Gateway (`world/gateway.py`)
+- `GatewayRoom` typeclass: A room that connects to another world
+- `TravelExit`: An exit that leads to another world
+- Properties: destination_url, destination_room, bridge_active, visitors
+
+### 2. Bridge API (`world/bridge_api.py`)
+- HTTP server on port 4003
+- Endpoints:
+  - `GET /bridge/state` — Get current world state
+  - `GET /bridge/health` — Check world health
+  - `POST /bridge/sync` — Sync state from another world
+
+### 3. Bridge Daemon (`world/bridge_daemon.py`)
+- Polls remote world for state changes
+- Syncs characters, events, and state
+- Usage: `python world/bridge_daemon.py --remote http://vps:4003 --poll 5`
+
+### 4. Migration Tool (`world/migrate.py`)
+- Export world state: `python world/migrate.py export --output world.json`
+- Import world state: `python world/migrate.py import --input world.json`
+
+## Setup
+
+### On Mac (Timmy's World)
+```bash
+cd ~/.timmy/evennia/timmy_world
+# Start bridge API
+python world/bridge_api.py &
+# Start bridge daemon
+python world/bridge_daemon.py --remote http://143.198.27.163:4003 --poll 5
+```
+
+### On VPS (The Wizard's Canon)
+```bash
+cd /root/workspace/timmy-academy
+# Start bridge API on port 4003
+python world/bridge_api.py &
+# Configure GatewayRoom with destination_url
+```
+
+## How It Works
+
+1. **Portal Rooms**: Both worlds have a GatewayRoom configured with destination_url
+2. **Bridge API**: Each world runs a bridge_api.py server
+3. **Bridge Daemon**: Polls remote world every 5 seconds
+4. **Travel Command**: Characters can use `travel [room]` to cross worlds
+5. **Sync**: Characters, events, and state sync between worlds
+
+## Events That Sync
+
+- Character arrivals/departures
+- Messages spoken in portal rooms
+- World events (fire, rain, growth)
+- Trust changes (limited sync)
+
+## Current Status
+
+- **Prototype**: Code structure created
+- **Not Tested**: Bridge not yet tested with real Evennia instances
+- **Next Steps**: 
+  1. Test bridge API on Mac world
+  2. Add GatewayRoom to Mac world (Threshold or Gate)
+  3. Configure destination_url to point to VPS
+  4. Test on VPS world
+  5. Test travel command
+  6. Test character sync
