Subject: [PATCH] feat: round-trip cipherSuites in share links and VMess QR
 code

The fork already round-trips its custom TLS fields (ech, vcn, pcs, pqv)
through share-link query parameters and the VMess QR-code JSON, but
cipherSuites was missing, so sharing a profile silently dropped it.

Add a "cs" query parameter to FmtBase import/export and a "cs" field to
VmessQRCode, mapped in VmessFmt parse/toUri, following the existing
pattern (emitted only when non-blank).
