Subject: [PATCH] fix: use agent mode for issues events with explicit prompts
 (#530)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes #528 - Issues events now correctly use agent mode when an explicit
prompt is provided in the workflow YAML, matching the behavior of PR events.

Previously, issues events would always use tag mode (with tracking comments)
even when a prompt was provided, creating inconsistent behavior compared to
pull request events which correctly used agent mode for automation.

The fix adds a check for explicit prompts before checking for triggers,
ensuring consistent mode selection across all event types.
