fix(marketing-plan): anonymize Olo reference example and sweep all leaks

Replaces all client-identifying details in the canonical example and
6 other reference files. Numbers and structural lessons preserved so
the example retains its teaching value.

Anonymizations applied:
- Client: Olo to Quietude (incl. all olo.app/space/audio/center domains)
- Team: Markus to Alex, Catarina to Sam, Corey Haines to Casey Reed,
  Shariq to Devon
- Product: Ona (AI) to Mira
- Repos: olo-* and Olo-Space/* to quietude-* and Quietude-Inc/*
- Endorser/investor specifics: Bryan Johnson to longevity-influencer
  (generic), Mark Pincus + OpenAI angels to consumer-tech angels,
  Andre Hurd/Daybreakers to partner-event-business
- Journal: Psychophysiology study to peer-reviewed psychophysiology study
- Substack: Coffee with Catarina to Sams newsletter

Other changes:
- Renamed references/example-olo.md to references/example-quietude.md
- Updated disclaimer at top of example to explain anonymization
- Updated VERSIONS.md changelog and plan-template.md reference
- Fixed an earlier blockquote that broke the AARRR table layout

Verified zero remaining identifying refs across all marketing-plan files.
