Closes#1039
- Add `preview` field to `RemoteObject` to capture CDP object previews
- Implement `format_console_arg` using preview data (value → preview → description)
- Store raw CDP args in `ConsoleEntry` and include in JSON output
- Skip typed `ConsoleApiCalledEvent` deserialization in favor of direct param extraction
- Unify console arg formatting between daemon (actions.rs) and stream (stream.rs)
Before: `console.log({userId: "abc", count: 42})` → `"Object"`
After: `console.log({userId: "abc", count: 42})` → `{userId: "abc", count: 42}`
JSON output now includes raw `args` array for programmatic access by AI agents.
