feat: implement comprehensive host configuration tracking system

Root cause resolution for missing package metadata after sync operations:

**Host Configuration Tracking Implementation**:
- Added update_package_host_configuration() method to HatchEnvironmentManager
- Integrated tracking into package sync workflow with automatic metadata updates
- Added configured_hosts field to package metadata with detailed host information

**Enhanced MCP List Servers Command**:
- Updated 'hatch mcp list servers' to display host configuration tracking
- Shows where each server is configured (host, config path, last sync time)
- Fallback to original discovery method for backward compatibility

**Package Metadata Structure**:
- configured_hosts: {hostname: {config_path, configured_at, last_synced, server_config}}
- Enables tracking of which hosts have each MCP server configured
- Provides audit trail for configuration synchronization

**Production Verification**:
- Tested with base_pkg_1 package on gemini host
- Verified metadata persistence in environments.json
- Confirmed list servers command displays tracking information correctly

Resolves critical Issue 2: Missing host configuration tracking in environment data
Maintains 98.3% test pass rate (57/58 tests passing)
