Root cause of all web UI bugs: web-ui depends on jae-ai and jae-agent-core
being compiled first. Without their dist/ output, all tool imports
(bash, browser, web-search, voice-tts, memory) silently fail,
causing the entire app to crash at load time.
New scripts:
- build:all: builds packages in correct order
- build:example: builds all + example app
- dev:example: builds all + starts dev server
