New package for joining SecuBox mesh networks from OpenWRT devices.
RPCD handler (/usr/libexec/rpcd/luci.masterlink):
- status: Current mesh membership state
- join: Join mesh with master_ip and token
- leave: Leave current mesh network
- info: Local node info (fingerprint, hostname, IP)
- verify: Verify master before joining
CLI tool (/usr/bin/sbx-mesh-join):
- URL parsing: sbx-mesh-join 'http://ip:7331/master-link/?token=xxx'
- Direct args: sbx-mesh-join 192.168.1.1 token123
- Auto-generates node fingerprint from MAC address
- Saves to UCI on success
LuCI interface (Services > Master-Link):
- Status display (connected/pending/disconnected)
- Invite URL/token input with Verify and Join buttons
- Leave mesh button when connected
- CLI usage help section
Also adds screenshot-capture.js for automated LuCI screenshots.
