A salamander finalmask carrying a packetSize range is Gecko obfs. The
hysteria2:// link generators already export it, but buildHysteriaProxy
copied only the password, so Clash/Mihomo received plain salamander and
could never complete the handshake against a Gecko server.
Emit mihomo's gecko form instead: obfs: gecko plus integer
obfs-min-packet-size / obfs-max-packet-size, validated by the same
parseHysteriaPacketSize bounds the URI export uses. A password-only mask
keeps the plain salamander output.
Closes#6822
- Export standard gecko obfs query params in hysteria2 share links
- Enforce packet size bounds across Go and TypeScript link handlers
- Persist uTLS None explicitly and initialize new TLS inbounds to chrome
- Tear down stackTun safely without closeMu deadlock against WriteNotify
