Goals end at achieved, not at an empty board: the goal-review loop

The board draining to 280/280 done left the company idle under a
still-active goal, with 24 markdown files and zero code as its life's work.
Two structural gaps caused it: goals had no lifecycle (status was written
once as 'active' and never read again — nothing re-engages anyone when the
last task closes), and nothing anywhere distinguished plans from product,
so every "engineering" objective closed on documents.

The loop, closed:
- tasks.origin (migration 055) records provenance: chat_wake for mention
  vehicles (backfilled from their runs), goal_review for checkpoints, null
  for real work. Chatter and checkpoints can therefore never count as
  progress.
- spawnGoalReviews (each worker tick): an active goal with zero open tasks
  and real progress since the last review gets ONE review task for the goal
  owner. The review demands evidence — list the workspace, read the code,
  run the tests; documents are how work starts, not proof it happened — and
  must end in exactly one of: complete_goal, or the next wave of tasks with
  requires_filesystem engineering. A review closed with neither spawns
  nothing: termination is structural, not a counter.
- complete_goal (CEO or goal owner) finally lets someone say a goal is
  achieved, audited.
- CEO and department-head voices now state the doctrine: a goal that
  promises software closes on code that builds and passes tests in the
  workspace, and implementation is delegated with requires_filesystem: true.

On the live profile this arms one review: the active platform goal has 0
open tasks and 21 real completed ones, so the CEO gets the checkpoint on
next launch and the company starts building instead of stopping.
