Add logging at all 4 levels: agent.execute, agent.act/observe/extract, CLICK/HOVER/SCROLL, and CDP

[pirate]

why

Clarify where the execution flow goes when stagehand runs by showing more detailed logs.

what changed

Adds a log line printed at the beginning and end of each layer's execution:

1. TASK: top-level user intent: when agent.execute('') is called (the initial entrypoint)
2. STEP: any call to .act(...) .extract() or .observe()
3. ACTION: any playwright or browser interaction api action dispatched, e.g. CLICK, HOVER, SCROLL, etc.
4. CDP MSG: any CDP websocket message sent to the browser

Uses the v3 logger (-vvv) for all these lines to avoid adding more noise to v1

test plan

Test by running pnpm tsx packages/core/examples/flowLoggingJourney.ts (make sure OPENAI_API_KEY is in env).
