fix(dev): skip deploy for plain agents without harnesses#1313
Merged

Conversation
`agentcore dev` was triggering a full CDK deploy even for plain agents (Strands, LangGraph, etc.) that only need a local dev server. This blocked users from iterating locally without AWS credentials/targets configured. Now `runCliDeploy()` is only invoked when the project has harnesses (cloud-dependent resources). Plain agents start the local server immediately. Closes aws#1189
