Add open wrapper to route URLs to embedded browser

Browse source 
When running `open https://...` inside a cmux terminal, the URL now
opens in the built-in browser panel instead of the system default
browser. Non-URL arguments and explicit flags pass through to
/usr/bin/open unchanged.

Closes #306
