fix(ext/node): TLSSocket.setServername throws typed errors#33744
Merged
Conversation
`TLSSocket.prototype.setServername` threw plain `TypeError`/`Error` without the `code` property that Node attaches. Replace with the existing `ERR_INVALID_ARG_TYPE` and `ERR_TLS_SNI_FROM_SERVER` Node- compat error classes (the latter was already defined in `internal/errors.ts`, just not used here). Fixes denoland#33743.
