Markets branch: 11-market tree, sub-market import, hero pipeline

Structure per the agency agreement (Joe/Christina, confirmed 2026-10-23):
/markets -> eleven market hero pages -> their sub-market pages; the
use-case level stays sections on the sub-market pages.

- new vitec:align-market-pages: renames 8 main market pages onto the
  agency names (slug change -> EXT:redirects), creates the 3 new markets,
  hides the dropped "Security & Surveillance" (records/stories
  untouched), reports unknown children. A child-slug pass realigns every
  child to <parent-slug>/<slugified-title> (DataHandler does not cascade
  slug changes; this also repaired the third embedded-slash slug,
  rtcc-/-rtic). --publish unhides the tree (dev convenience; element
  shells stay hidden)
- sub-market import: all 24 agency workbooks applied (4 existing pages,
  20 created) - their Meta sheets were clones of Corporate Environments
  (record_uid 32) and were repaired beforehand (market/sub-market set,
  record_uid 0; the record taxonomy alignment is a separate step)
- SubmarketWorkbookImporter: page-properties parity (og/twitter titles
  and descriptions, canonical, abstract from the intro copy) and a
  placeholder upgrade pass - pages created in the same run only get the
  generic grey (their uid is still NEW), the re-run swaps it for the
  numbered per-page placeholder
- new market hero pipeline: frontend layout 23 "Market Hero Page"
  (zones hero=colPos1, main=colPos0), Import\MarketHeroPageImporter +
  vitec:import-market-hero-workbooks (inbox migrations/markethero_xlsx_in,
  gitignored). Hero H1 travels on the introparagraph header (markethero
  has no headline field), the hero CTA anchors #submarkets, sub-market
  cards link their child page via t3://page, customerlogos and
  usecaselist ship hidden until filled editorially, prefooter ctabanner;
  full page-properties set with 11 curated keyword sets
- applied end to end and live-verified (layout 23 heroes with linked
  cards, layout 21 sub pages with all six colPos groups, clean slugs)
- spec v1.25

Open: market RECORD taxonomy (story badges / Solr facets still use the
old 9 mains), featured product "ISR Video Mission Commander" has no
record, the /markets main page workbook (template 2) is a separate flow.
