Add /explore redirect route that maps Honcho's deep-link shape
(?workspace=...&view=...&session=...) onto our existing flat routes,
so any app.honcho.dev URL works against a self-hosted instance by
swapping the host.
Wire tauri-plugin-deep-link to register the openconcho:// scheme on
desktop and forward incoming URLs into the router on launch and at
runtime.
http://** uses ** in hostname which is not valid URL Pattern spec.
Hostname wildcard is * (not **); non-default ports require the *:*
host:port form. Add all four variants to cover http/https on both
default and non-default ports.
