Synchronizers Map not persisted - rescans on every restart

[Retengart]

Problem

this.synchronizers Map in Context class is in-memory only. After MCP server restart, synchronizers are recreated from scratch.

Current Behavior

// handlers.ts:320-330
const synchronizer = this.synchronizers.get(collectionName);
if (!synchronizer) {
    // Recreate synchronizer - loses previous file hash state
    const newSynchronizer = new FileSynchronizer(codebasePath, this.ignorePatterns);
    await newSynchronizer.initialize();
}

initialize() regenerates all file hashes.

Impact

First background sync after restart scans entire codebase to rebuild file hash map, even though merkle files exist on disk.

Expected Behavior

FileSynchronizer already persists to ~/.context/merkle/<hash>.json. The synchronizers Map should be reconstructed from these files on startup.

Location

• packages/mcp/src/handlers.ts:320-330
• packages/core/src/sync/synchronizer.ts:217-221 - initialize() loads from disk but Map not restored
