feat(propose,extract,cli): a title that ends in a number, and a converter's own anchor in a concept id

Round 9: the four rests in STATE's NESTE that needed no operator decision.

CLAUSE 1 CLASSIFIED BY THE NUMBER, NOT THE TITLE. `_TRAILING_PAGE_NUMBER`
admitted a candidate into a contents run by asking whether the title ended in
an integer -- a question about the number. A drawing's dimension chain, a
schematic's labels, a door schedule, a coordinate column and a soil-layer
table all end in integers and name nothing. Measured over the 43-document
corpus: 68 candidates discarded over 11 of 39 readable documents, of which
19 over 5 documents are data rows.

That corrects round 8's own decomposition. Its "four misclassified numeric
tables and seven real contents listings" needs each document on one side, and
two of the eleven are both. Read across all 68 titles rather than the
three-title sample: 5 documents carry a data row, 8 carry a real entry.

`--contents-name` requires a NAME to survive stripping the page number. The
threshold is SWEPT, not chosen, and collapses at both ends: at an alphabetic
run of 1 a door schedule keeps a stray `V` and 13 of 19 are rescued; at 3 the
two-letter section name `VA` stops being a name, falls out of run membership,
and takes `RIB`, `MMI` and `Tittelfelt` below `CONTENTS_RUN` with it -- one
acronym costing four REAL entries. At 2: 16 of 19 rescued, 0 of 49 regressed.
The three not rescued carry a real word and are named rather than rounded off.

THE CONVERTER'S ANCHOR WAS IN THE CONCEPT ID. Pandoc writes a sheet as
`## <name> {#sheet-N}` and a titled slide as `## <title> {#slide-N}`. Because
a filename is reduced FROM the title, the anchor reached both. Operator
authorised the strip 2026-09-09 after the exposure was counted: 2 of 810
concepts on the previous default bundle, 2 of 1108 on Arm B, 1 of 26 on the
operator's folder. Two ids renamed, one of which `portfolio-optimiser` has
cited in writing; both are in the report so that message can be sent.

One rule in one function, read by BOTH title-forming sites -- a rule in only
one would leave the id and the title naming the same concept differently. The
known-negative is the point: `Mal for {kundenavn}` is a title an author wrote.

odt/rtf/pptx MEASURED END TO END FOR THE FIRST TIME, on hand-built documents,
because the corpus denominator is genuinely zero (86 files: 66 pdf, 10 docx,
4 xlsx, 2 zip, 2 smc, 2 doc). `_EVIDENCE` gains a third class rather than
stretching an existing one: `constructed` means the row has met a document,
but not one anyone wrote for their own purposes. odt 1 of 1 declared headings;
pptx 2 of 2 on a deck that declares slide titles and 0 of 2 on one that does
not -- round 7's reading of pptx was a fixture property, not the format; rtf
0 segments, because the container has no heading style and the author's title
is bold text. rtf is the one open finding.

ACCEPTANCE, all four. The 12-position reference is label-identical in BOTH
readings (pdf 7/8, docx 3/3, xlsx 0/1 or 1/1, sheet 10/12 or 11/12). One K2
bundle carrying both changes: 453 concepts / 865 md, hit@8 [1,1,1,1,1,None]
on it AND on Arm B, with the known-negative still reproducing on the new
bytes. `okf project` byte-equal to `okf build`, `diff -r` empty. Consumer
cost is a re-run: 436/832 -> 453/865, digest 21af4a1aa98315cf.

Three published numbers corrected: README's 596 tests (1515), README's "15
concepts out" for `okf project` (that was the O6 defect; it is 26), and O6's
print-mode method, which does not reproduce without --allowedTools.
