offset with an IANA time-zone identifier, propagating that value through
ChatRequest, Turn, and Agent. Update the prompt to require calculating the
offset for the requested calendar date, while retaining the numeric offset only
as the current-time display value if needed.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Send an IANA time zone for named-date queries.
getTimezoneOffset() only describes the offset when the request is sent. It cannot identify the offset for a named date across a daylight-saving transition. For example, a client in America/New_York can send -240 in summer, while January 1 uses -300. Warp then computes the January UTC boundary one hour early and can include or exclude incorrect traffic.
Send an IANA time-zone identifier with the request. Propagate it through ChatRequest, Turn, and Agent. Update the prompt to require the offset that applies on the requested calendar date. Keep the numeric offset as the current-time display value if needed.
