Pull request overview

Adds sessions-window actions to (1) prompt the chat to fix failed CI checks for the active session and (2) submit pending agent feedback for the active session, wiring both into context keys/menus to appear only when relevant.

Changes:

• Introduces Fix CI Checks action + active-session failed-checks context key.
• Refactors CI check helper logic to be shared between the CI status widget and the new action.
• Adds Submit Feedback action for the active session and dynamically registers a menu item showing the pending feedback count.
