chore: align non-product files to 4.73.1 release

Take the released (develop) version of CLAUDE.md, NotificationIntentHandler.kt,

product customizations, so the single-server release merge should adopt the
released content. Leaves the diff vs develop as whitelabel + version only.

 ## Code Style
 
 - **Prettier**: tabs, single quotes, 130 char width, no trailing commas, arrow parens avoid, bracket same line
