Fix: Fix incorrect command formatting in agent context file

The issue is that `sed` treats `&&` as a placeholder instead of a regular character. So in the CLAUDE.md file's "Commands" section, it incorrectly shows:

`npm test [ONLY COMMANDS FOR ACTIVE TECHNOLOGIES][ONLY COMMANDS FOR ACTIVE TECHNOLOGIES] npm run lint`

instead of the correct:

`npm test && npm run lint`
