Note

Medium Risk
New issues and PRs will no longer be auto-added to the kanban; items may be missing from the board until added manually or caught by reconcile, which can affect FR gate and board hygiene.

Overview
Removes the add-to-kanban workflow that ran on newly opened/reopened issues and PRs (including ready_for_review) and called actions/add-to-project to add them to org project #2 (engineer kanban) using PROJECTS_KANBAN_TOKEN.

That automatic board enrollment stops with this change. Other workflows that still use the same token for FR gating, deploy advancement, WIP checks, and reconciliation are unchanged.

👋 Heads-up — Code review queue is at 50 / 30

Above the WIP limit. The team convention is to review existing PRs before opening new work.
