chore: add detailed logs to evaluateInEngine262.runner.mjs

Browse Source 
- Insert console.error statements to trace loading, initialization, execution, and mark collection.
- Log creation of agent and realm, trace start/stop, and code execution progress.
- Output captured mark count.
- Simplify fatal error handling with a single error message variable and console.error output.
