Yuval Dinodia 89881b6611 fix(irc): long non-ASCII messages are silently truncated at the 512-byte line limit (#99138)
* fix(irc): chunk PRIVMSG by UTF-8 byte budget so long non-ASCII messages are not truncated

IRC caps a full protocol line at 512 bytes, but sendPrivmsg split outbound
text by UTF-16 code units against the 350 char default. Multi-byte text such
as CJK or emoji produced lines far beyond 512 bytes and servers silently
dropped the tail of every oversized chunk. The chunker now also enforces a
UTF-8 byte budget derived from the line framing overhead, splitting on code
point boundaries and preferring spaces, while ASCII chunking is unchanged.

* test(irc): move loopback IRC server helper to shared test helpers

The colocated node:net import tripped the network-runtime-boundary PR diff
scan for extensions/irc/src. The loopback server now lives in test/helpers,
outside the scanned network runtime paths, and the CJK, emoji, and ASCII
chunking cases keep driving the real client over a real TCP socket.

* fix(irc): decouple byte budget from character cap and move loopback helper to irc test-support

The byte budget is now derived only from the 512-byte line limit and framing
overhead, independent of messageChunkMaxChars, so low character caps with
multibyte text keep advancing instead of dropping the message. The loopback
IRC server helper moves from test/helpers to the extension-local package-root
test-support surface so extension tests stay off repo helper bridges and raw
socket use stays outside extensions/irc/src.

* fix(irc): enforce UTF-8 wire limits

* test(irc): satisfy loopback harness lint

* test(irc): avoid implicit Promise return

* test(irc): handle loopback close errors

* fix(irc): preserve boundary word splitting
