fix(fork-terminal): align Socket send types with upstream Uint8Array

Upstream changed Socket.send to use plain Uint8Array (resolved as
Uint8Array<ArrayBufferLike>) while fork types used the narrower
Uint8Array<ArrayBuffer>. This caused a TS2345 assignability error
when passing PtySocket to Pty.connect. Widen the fork Socket/PtySocket
send signatures to match.

fix: align fork-terminal pty-auth-hook with upstream Socket type

Upstream's terminal cross-talk fix (anomalyco#14184) changed Pty.connect to
require a Socket type with a `data` property and now uses ws.raw
instead of the WSContext wrapper. Update createPtyWebSocketHandlers
to extract and validate ws.raw before passing it to the connect
callback, matching the upstream pattern.
