The Clash stream builder computed tlsSettings["pin-sha256"] from the inbound's
pinnedPeerCertSha256, but applySecurity's tls case never copied it onto the
proxy, so it was written with no reader and silently dropped. Clash subscribers
lost certificate pinning while JSON subscribers kept it. Surface pin-sha256 on
the proxy in the tls case, matching the JSON emitter.
genHy asserted stream["hysteriaSettings"].(map[string]any) without the comma-ok
form, so a hysteria inbound whose StreamSettings omit the hysteriaSettings key
(a valid, representable shape the raw generator renders fine) panicked and 500ed
the entire JSON subscription. Use comma-ok; the downstream reads already guard
each key, so a nil map degrades gracefully.
The raw share-link generators used unchecked type assertions and unguarded
array indexing: an empty Reality shortIds/serverNames array (random.Num(0)
panics), a tcp-http header with no request block or an empty request.path, a
grpc block missing its keys, empty stream settings, and a non-string Host
header all panicked mid-generation. Because getSubs loops every client's link
with no recover, one such client 500s the entire subscription for everyone. The
sibling JSON, Clash and frontend generators already guard these; make the raw
generators match with comma-ok assertions and length checks.
