CB-WP-0004 T02: make task-done — close a task on measured numbers

Browse source 
Replaces the three hand-done steps of a task close (46 turns, $11.52 per
CB-RES-0003): the heredoc flipping status in the workplan file, the
hand-written hub call, and the hand-typed token counts.

The third is the reason this task exists. Every update_task_status this
repo produced carried estimated tokens_in/tokens_out — in a project whose
central finding is that estimated token counts are worthless. task-done
reads the measured figure from the transcripts, or refuses; there is no
path through it that emits an estimate.

cb-cost gains by_task_detail: cost, response count, model histogram and
token components per task. task-done imports cb-cost rather than parsing
its printed table, so the hub figure is not a copy that can drift from
its source.

The positive control found a real defect before the tool ran once.
Attribution keyed on a bare T\d\d from the commit subject, so CB-WP-0002
T01, CB-WP-0003 T01 and CB-WP-0004 T01 shared a bucket: the self-test
reported $12.10 for "T01" where the qualified figure is $2.33. That 5.2x
overstatement would have been pushed to the hub as a *measured* number —
the same fiction in a new form. task_label() now keys qualified subjects
on the full id and leaves unqualified ones bare rather than
retro-assigning them to a workplan. The pinned $93.15 benchmark is
unchanged, so historical attribution was not disturbed.

Fourth instance of trusted arithmetic: a number believed because a
program produced it rather than a hand.

Refusals, all exercised by --self-test: unknown id, typo'd id,
already-done task, missing state_hub_task_id, no measured spend, and a
status flip that produced no change.
