3.30.8

Fixed TypeScript errors caused by using 'connectionRecord' instead of 'record' in TLS renegotiation handlers.
The variable name mistake occurred when moving and restructuring the TLS handshake detection code.

 ## 2025-03-11 - 3.30.7 - fix(PortProxy)
 Improve TLS renegotiation SNI handling by first checking if the new SNI is allowed under the existing domain config. If not, attempt to find an alternative domain config and update the locked domain accordingly; otherwise, terminate the connection on SNI mismatch.
