Completes the migration begun on 2026-08-25, which covered active workplans
only. The archived copies kept their historical identifiers, and three
repositories shared one number space — so their task identifiers collided,
blocking task-level projection reset for those workplans.
Numbering continues each repository's active sequence rather than restarting,
so no identifier is reused. Projection UUIDs are re-derived from the new
canonical ids.
