Set up a beads issue-tracking board in any repo. Supports three modes: local (embedded Dolt, no server needed), shared (team Dolt SQL server), and shared+remote (shared server with DoltHub sync). Use when initializing beads in a new repo, connecting to a shared Dolt server, troubleshooting bd init, or migrating from embedded to shared mode. Triggers on "set up beads", "create a board", "init beads", "connect to the beads server", "new beads board", or "set up issue tracking".
