Subject: [PATCH] fix: include day of week in date/time context injection
 (#4629)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The system prompt now displays the full formatted time including the
day of week (e.g., "Current time: Monday, January 5th, 2026 — 3:26 PM
(America/Chicago)") instead of just showing the timezone.
