feat(layout-review): journey-level redesign — front door, taught order, consistency

Addresses the journey-level review (the app felt like 12 tools sharing a
stylesheet, not one guided product). File-partitioned changes:

Navigation (shell.js): rename Home -> "Start here" with front-door
emphasis (.dt-nav-start); reorder Data Cleaners into pipeline order
(Clean Text -> Standardize -> Fix Missing -> Find Duplicates); new
"Finance" group (Reconcile, PDF to CSV); all stubs moved to a bottom
"Coming soon" group, no longer interleaved with working tools.

Front door (home.html): a prominent primary "Clean these files for me"
that runs the recommended pipeline in order, above the existing
per-finding cards (reframed as "fix one thing at a time").

Shared tokens (app.css): .dt-next-step suggestion strip + .dt-nav-start.

Teach the order: a slim .dt-next-step strip at the end of each linear
cleaner page points to the next pipeline step (Map Columns -> Start here;
orchestrator/Finance pages correctly omit it).

Local-first: the green "Runs 100% locally" pill now sits in every working
tool page's header (home + 8 tools), where client data is entered.

Plain English: jargon relabeled on input controls (coerce, E.164,
NFC/NFKC, sentinels, survivor rule), technical terms kept in tooltips and
audit/output cells only.

Stubs (06/08/07): rebuilt to one identical skeleton — info line + plain
feature list + a real "Notify me when this ships" button; every disabled
control and uploader removed (a dimmed dropzone reads as broken).

Intake: full dropzone+chip replaced with the compact "Using <file>" banner
on Clean Text, Fix Missing, Find Duplicates, and both Reconcile sides.
