chore: remove all nJAMS references from the live site

Per Hendrik's direction, no nJAMS references on the website. The
founder pedigree claim now stands on the years and the customer
segment ("15 years building integration monitoring for banks,
insurers, and logistics operators") without naming a prior product.

Changes:
- src/components/sections/SocialProofStrip.astro: drop the
  ' · ex-nJAMS' suffix from the founder attribution; collapse the
  multi-step PENDING comment into a single-line founder-name TODO.
- src/components/sections/WhyUs.astro: drop the trademark-review
  comment (no longer relevant — the body text never named the
  prior product, only the comment did).
- OPERATOR-CHECKLIST.md: remove the 'Why us / nJAMS wording review'
  pre-publish task.  Also rename the adjacent 'MID-tier retention'
  TODO to 'Starter-tier retention' to match the relaunched tier
  taxonomy.
- docs/superpowers/specs/2026-04-25-cameleer-website-relaunch-design.md:
  update §4, §6.2, §12 to reflect the removed wording.  Only the
  founder-name placeholder remains as a pre-publish blocker.

Historical specs / plans under docs/superpowers/{specs,plans}/
keep their original wording — they're records of past decisions
and are not on the website.
