fix: improve logger output by removing emojis and excessive indentation (#229)

- Remove emoji icons from log levels for cleaner terminal output
- Disable column alignment to reduce excessive spacing
- Maintain unlimited depth inspection for complex objects
- Keep syntax highlighting for better readability
- Regenerate deno.lock with optimized dependency structure (1701→65 lines)
