feat: Tier B operator scaffolding — bundle, copy SoT, posts, emails

Pick up and finish yesterday's cut-off Tier B pass.

- build/: PyInstaller scaffold (datatools.spec + launcher.py +
  hook-streamlit.py + README) — folder-mode bundle, locked
  127.0.0.1, per-OS recipe
- marketing/COPY.md: single source of truth for every customer-facing
  string — landing H1/sub/CTAs, demo CTAs, email subjects, Gumroad
  listing, banned phrases
- marketing/community-posts/: 9 drafts (3 posts × 3 niches:
  bookkeeper, revops, shopify-pet) — story / tip / soft-offer
- marketing/emails/: 18 drafts (Gumroad delivery + 5-touch
  onboarding × 3 niches), per-niche segmentation guidance
- docs/NEXT-STEPS.md: flip 2.2 / 2.4 / 3.1 / 3.4 to done with
  pointers to the new assets; add Phase 0 inventory rows
- .gitignore: narrow `build/` ignore so PyInstaller spec + launcher
  + hooks get tracked, only generated artifacts (build/build/,
  build/__pycache__/, build/dist/) stay ignored

+## Title
+
+The 30-second pre-import check that catches LinkedIn-scrape duplicates before they hit HubSpot
+
+## Body
+
+Before you import a LinkedIn scrape (Apollo, Lusha, Cognism — same problem) into HubSpot:
+
+Open the file. Sort by `email`. Look for blanks.
+
+LinkedIn-sourced rows often have *no email* — just name + company + LinkedIn URL. If you import them as-is, HubSpot creates a new contact for each one. The next time someone fills your webform with the same name + company, HubSpot creates *another* new contact, because there's no key to match on.
+
+Two-minute fix: before import, generate a synthetic dedupe key as `lower(first_name)|lower(last_name)|domain(company_url)`. Sort by it. Anything with >1 row is a likely dupe — review and merge before HubSpot ever sees it.
+
+If you're doing this monthly across multiple lead sources and want to automate it (plus phone normalization, fuzzy matching, the whole pipeline), I built a $49 desktop tool: datatools.app/revops. Local — your prospect list never goes to a server.
