Improve Intent Classification for Early Departures / Shortened Stays

Problem: The current intent classifier misidentifies "early departure" or "shortened stay" requests as "Late Check-out". For example, a guest asking for a partial refund to check out early was detected as requesting a late check-out, triggering an incorrect auto-reply with the late check-out fee table.

Impact: Guests receive irrelevant information, creating a poor guest experience and requiring manual correction by the host.

Proposed Solution:

• Update the classifier to ensure "check out early", "leave earlier", and "cut the trip short" are not detected as "Late Check-out".
• Add a dedicated "Early check-out / shortened stay" intent.
• Allow hosts to provide negative examples or exclusions per intent to prevent misclassifications.
