Enables multi-user project collaboration mirroring the shared calendar pattern. Includes ProjectMember model with permission levels, task assignment with auto-membership, optimistic locking, field allowlist for assignees, disconnect cascade, delta polling for projects and calendars, and full frontend integration with share sheet, assignment picker, permission gating, and notification handling. Migrations: 057 (indexes + version + comment user_id), 058 (project_members), 059 (project_task_assignments) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
