Primer freshness: cited Overwolf docs pages changed

[github-actions]

The scheduled freshness check found drift between the primer's cited pages and the committed baseline. Re-read the pages below, update references/overwolf-platform-primer.md if needed (see CONTRIBUTING.md), then run node scripts/check-primer-freshness.mjs --update and commit the new baseline.

Primer sources drifted since 2026-06-09:

  CHANGED    https://dev.overwolf.com/ow-native/guides/general-tech/using-game-events-in-your-app
  CHANGED    https://dev.overwolf.com/ow-native/live-game-data-gep/live-game-data-gep-intro
  CHANGED    https://dev.overwolf.com/ow-native/reference/manifest/manifest-json

Re-read the changed pages, update references/overwolf-platform-primer.md if needed
(see CONTRIBUTING.md), then run this script with --update to accept the new baseline.
