- Migrate $protocol_settings['key'] to data_get($protocol_settings, 'key') across General, SingBox, Shadowrocket, Surfboard, QuantumultX
- Prevents PHP 8 Undefined array key fatal errors when optional protocol_settings fields are missing
- Same class of bug that caused #735
- Implement Workerman-based `xboard:ws-server` for real-time node synchronization.
- Support custom routes, outbounds, and certificate configurations via JSON.
- Optimize scheduled tasks with `lazyById` to minimize memory footprint.
- Enhance reactivity using Observers for `Plan`, `Server`, and `ServerRoute`.
- Expand protocol support for `httpupgrade`, `h2`, and `mieru`.
- Only add HTTP transport when network_settings.header.type is not 'none'
- Use pure TCP (null transport) when header type is 'none' or unset
- Align with General protocol implementation and VMess specification
This prevents unnecessary HTTP transport layer when using pure TCP.
