feat(propose,cli): typography as a reserve, and the two of our own numbers it took to measure it

K3 round 5. Three questions, three answers, and two of them correct a figure
this repository published.

RETRIEVAL FIRST, because it could have reversed a default. hit@8 over the six
questions on BOTH K2 bundles -- Arm B at 629 concepts and the shipped default
at 492 -- is 5 of 6 with ranks 1,1,1,1,1,- on each, so 0 of 6 rows lost. The
order's rule reverses `--unit-fold` at >= 2 of 6; it does not fire, and the
default stands. The gold sets shrink (49->26, 20->17, 43->36, 11->18) while
every rank holds at 1, which is the fold merging concepts rather than removing
a document from the top.

TWO PUBLISHED NUMBERS CORRECTED, both ours. The S7 candidate ranks 96 of 629
and 159 of 492 were measured with the cost vocabulary passed to
`concept_scores` and NOT to `document_scores`, while `build_payload` passes it
to both; scored the way the shipped payload scores it, the same concept is 10
of 629 and 19 of 492. And round 4 attributed its non-delivery to the default
move -- measured here, it is not delivered on the Arm B bundle either, for a
different reason (knapsack eviction at 68 046 bytes of a 120 000 budget, versus
`below_k`). That column had been inherited from round 3's own build, never
re-measured.

`--pdf-headings font-reserve`, OFF, and the hypothesis behind it is falsified
by its own condition rather than by a score: position 7, the one position the
flag exists for, has THREE outline runs, so the reserve is silent there at
every minimum. It changes 0 of 12 cells on the reference and reaches 4 of 39
corpus documents, none of them rated. Built anyway because it was authorised
and because the condition is now measured rather than assumed. The predicate
lives in one place (`propose.heading_reserve_applies`) and the door receives it
as a callable, like `gate`: a plan indexes the exact string it was proposed
against, so a reserve firing on one side only would make every document it
touches a coded rejection.

The `xlsx` re-reading is confirmed on the artifact -- 11 `rule:sheet-section`
units plus 1 `rule:table-block` ingress -- but the number alone makes the cell
worse (distance 1 -> 2), because the criterion counts that ingress as a table
that should have been merged. A hit needs both halves ratified, and the
reference is the operator's.

`--sheet-section-rows` as a default: three cells better and none worse on the
twelve positions, but the K2 control moves -- row 1's gold document splits 1 ->
12 concepts and its best concept ranks 2 instead of 1. Condition not met,
default not moved.

Default build byte-identical before and after (`diff -r`, 30 md files).
Suite 1441 -> 1449; three of the eight were red first.
