* feat(sub): warn when salamander settings cannot reach the client
A hysteria2 share link carries obfuscation as obfs=salamander plus
obfs-password, and nothing else. Xray's finalmask accepts more than that —
packetSize among them — and those extra settings change what the server expects
on the wire. The emitted URI then looks complete but describes a server the
client cannot reach: every standard client applies plain salamander, the server
drops the packets, and the failure is silent on both ends.
Log the unexpressible keys when building such a link, naming the inbound, so the
cause is visible instead of appearing as a client-side problem.
* fix(sub): deduplicate salamander warnings
