fix(cli): don't re-run listeners when replaying corked messages

[sai-ray]

Messages emitted while logging is corked are buffered and replayed through notify() when the cork releases. notify() re-ran the message listeners on that replay, so a listener that transforms a message (e.g. a rewrite) ran a second time on its own already-transformed output.

This skips applyMessageListeners while corkReplaying, matching the existing guard that already skips observers on replay. Listeners now run exactly once, on the first pass.

The visible case: under --yes, the auto-confirm suffix is added (via writeMessage) after listeners run, while corked. On replay, a rewrite listener on that request code would clobber the suffix. This is latent on main today (nothing registers such a listener yet) but blocks the cdk deploy reroute in #1585.

Test plan

• Unit test in test/cli/io-host/cli-io-host.test.ts: a rewrite listener fires once through a corked replay, not again on the replayed message. Verified it fails without the fix (listener runs twice) and passes with it.
