Milestone 1: Add Numbers Zapier app, /v1/add, developer setup guide

packages/verae-activate is pushable with zapier-platform 19.1.0: local
Add Numbers (number1+number2=sum) needs no hosted API. zapier-platform
validate is clean (0 warnings). zappier POST /v1/add is a free metered
endpoint for the optional hosted path.

Tests: verae-activate 7/7, zappier 176/176, verae-zapier 5/5, middleware
gate 1 11/11. Morning steps: docs/04-activate/SETUP-ZAPIER-DEVELOPER.md

Learned: perform runs on Zapier cloud so arithmetic needs no public URL;
CLI and zapier-platform-core majors must match; do not mix zapier-sdk.
