generate output uses ${APP_URL}, not testmd's {{VAR}} syntax

[komal-lt]

Summary

TCG-generated tests use ${APP_URL}, a different placeholder syntax from testmd's {{VAR}} / variables-file system.

kane-cli generate ... --save writes *_test.md files whose steps reference the app URL as ${APP_URL} (shell-style). testmd's own variable system uses {{VAR}} resolved from the variables store. So a user must hand-edit every generated test to fit the run-time variable model.

Ask

Use consistent placeholder syntax across generate ↔ testmd run so the generate→run loop needs no manual rewrite.

Env

kane-cli 0.4.4, generate --save + testmd run.
