The proofread checkpoint gets its place: nav order, badge, and a rename

Eric's observation: cleaning up raw reads happens BEFORE resolve, but
the app ordered Review ahead of Catalog and never said proofreading was
a step at all. The pipeline has two human checkpoints — proofread the
reads (after extract), decide the matches (after resolve) — and now the
app says so: the sidebar runs Pipeline, Photos, Titles, Review, Queue,
Library, Help in true workflow order; the Titles page (né Catalog — the
old name suggested a finished collection, which is the Library's job;
/catalog redirects) gets a badge counting unresolved shaky reads; an
edit marks its entry human-verified so the badge drains as you
proofread; the extract stage card nudges toward the proofread before
resolving; and the Help flow is rewritten as six stages + two
checkpoints with the loop called out.

 ### Fixing what the model gets wrong
 
-Vision reads aren't perfect, and you know things the photos don't show. The Catalog page lets you **edit** a title (fix a misspelling, add publisher/edition/year/language cues you know offhand), **split** a line into per-photo copies when one title is actually several boxes, and **remove** lines that aren't games at all. Every one of these is durable: the decision lands in a small committed store (`data/title_edits.json`, `data/title_splits.json`, `data/title_removals.json`) that is replayed on every rebuild — re-running extract or resolve can never undo your curation. Undo any decision by deleting its record from the store. The in-app **Help** page documents all of it.
