  1. fix(devtools): use explicit env flag for dev mode detection (#12694) 

    ## Summary
- Replace path-based `/dist/` check with an explicit
`AI_SDK_DEVTOOLS_DEV` env flag for dev mode detection
- Prevents false positives in monorepos (NX, Turborepo) where `/dist/`
paths are common in the workspace
- The `dev:api` script now sets `AI_SDK_DEVTOOLS_DEV=true`
automatically; production mode is the default when the flag is unset
