Description

In order to validate offline mode in v0,
as a Marathon developer,
I need to create a demo that disables networking, makes local changes, re-enables networking, and verifies changes sync correctly.

Acceptance Criteria

Scenario: Networking can be disabled
  Given networking is enabled
  When the disable networking command is executed
  Then the client operates in local-only mode

Scenario: Local changes persist when offline
  Given networking is disabled
  When local changes are made
  Then changes are saved locally

Scenario: Networking can be re-enabled
  Given networking is disabled
  When the enable networking command is executed
  Then the client reconnects to the session

Scenario: Local changes sync when reconnected
  Given local changes were made while offline
  When networking is re-enabled
  Then local changes sync with other clients

Technical Notes

Dependencies: #129 (CRDT sync demo), #131 (session lifecycle)
Approach:
- Add networking toggle command to demo client
- Queue local changes while offline
- Sync queued changes on reconnect
- Verify no state loss during toggle
Files affected:
- Modify: crates/libmarathon/src/network/mod.rs (add enable/disable)
- Modify: CRDT sync demo (add networking toggle command)

Additional Context

Part of v0 Core Tech Validation. Desktop only (macOS). Validates that the game can work offline.
