De-slop pass: dead plumbing out, comments stop narrating history

Eric asked whether AI residue had crept in since the last credibility
pass. It had, in two forms — both descendants of the audit's
"row-edit flow is collid-exact now" fix, which corrected upload.py but
not everyone who believed the old constraint:

The deferral scaffolding survived its own removal: build_queue still
returned a permanently-empty deferred list, run_upload still unpacked
it and carried a dead echo branch repeating the DISPROVEN claim ("the
row-edit flow can't target a collid"). And diff.py held a vestigial
guard on the same false premise, refusing to upgrade a versionless
copy whenever a sibling carried a version and telling the human to do
it by hand — the collid-exact editor makes that upgrade safe, so the
guard cost a real capability and its test now pins the opposite.

A comment audit (13 findings, verified line-by-line) cleaned the rest:
the webreview docstring counted six pages of seven and claimed
"localhost only" (--lan exists); the nav comment still said "catalog"
for the page renamed Titles; extract's docstring credited "Claude
vision" though any OpenAI-compatible endpoint dispatches; and five
comments narrated retired bugs ("the original bug", "why the old
guess quit after page one", "made the count go negative") — each
rewritten as the present-tense constraint or trimmed, per the
standing rule: comments state what the code can't show, never how it
got that way.
