feat(p22): declare_requirement answers with a COMPARISON, not a confirmation

P19 DEL A made a direction name the requirement that binds it; P20/A1 made the reply carry the
DOCUMENT's own title and number instead of echoing the caller's arguments. Re-measured at the head
of this session against the six round-5 debate traces: requirement_hit is 0 of 20 approach rows and
0 of 12 declarations -- the third round in a row at zero. P21/C1 made the runs LOOK first and it
worked on its own terms (distinct documents before a declaration went 1,1,1,2,5,13 -> 3,3,5,7,11,12)
and the hit did not move. The runs were made to read MORE, not righter.

The reply now compares: it names the directions the run was commissioned to pursue and says which
of their words appear in the declared document's own title and number, or that none do.

A REPORT, never a gate -- the declaration is recorded either way, because a requirement can bind a
measure without sharing a word with the name someone gave it, which is exactly how the alternative
rule the C1 measurement rejected failed one rung over. The words compared are the DOCUMENT's, never
`ref`: a comparison against the caller's own argument can only ever agree. Matching is generous in
both directions, and that failure direction is chosen -- a false "no overlap" pushes a model away
from a declaration that was right, a false "overlap" merely keeps the report quiet.

MEASURED BEFORE IT WAS BUILT, offline against the six traces as the order required (no paid calls
in DEL B): the rule speaks on 10 of 12 declarations and stays quiet on 2. A rule that spoke on 12
of 12, or on 0 of 12, could not tell the two classes apart.

`labels` defaults to empty, so every call site written before today is byte-identical and the three
keys are ABSENT rather than empty -- "there was nothing to compare against" and "we compared and
found nothing" are different facts. RUN-level, as the declaration itself is (P19 A4).

Also re-measured: the order cited requirement_hit as "0 of 12". The field is per APPROACH (0 of 20);
12 is the number of DECLARATIONS (7 distinct, 0 hits). Both zero, so the conclusion stands, but they
are two populations.

Load-bearing MEASURED (tests/test_requirement_comparison_loadbearing.py, 8 arms), eight mutations
all red against the WHOLE suite + green control 1881/5 (from 1873/5, superset, 0 removed) and
golden demo-transcript.stdout BYTE-UNCHANGED (shasum -a 1 of the CONTENT =
ea8c534773acdbe41ae68f2c55724d69aaf8be4f): B1 detach the run.py wiring (1 red, that arm alone) -
B2 always report an overlap (5) - B3 never report one (2) - B4 compare against the caller's ref
(1, that arm alone) - B5 make it a gate (5) - B6 emit the keys with no directions (2, one an OLDER
independent witness) - B7 exact token equality instead of substring (1) - B8 drop the minimum word
length (3).

Honesty limits, stated: no LIVE model has read the comparison yet (DEL D is the measurement); the
report cannot say a requirement IS right, only that it shares no word with the direction; and
finding 4 (`named` 1/20) is this same matter from the other side, so DEL D measures it.
