Review comments at @packages/cli/src/commands/dev/devHandler.ts:
- Around line 310-311: Update the warning text in the `devHandler` fallback so
it describes falling back to classic dev-server mode without promising that both
API and web servers will run; leave the fallback job selection unchanged.

Summary
cedar dev --udruns the classic api and web dev servers instead of the unified one when any of these is true:apiandwebapi/src/server.ts)The flag is dropped without any output in these cases. This PR prints a one-line warning naming the reason. Behavior is otherwise unchanged; the classic servers still start.
Testing
yarn workspace @cedarjs/cli vitest --run src/commands/dev/__tests__/dev.test.ts(new tests for the server-file and single-workspace warnings, and for no warning when unified dev runs)prettier --checkandeslintonpackages/cli/src/commands/dev
