refactor: simplify event API method names for better ergonomics

- Rename verbose method names to shorter, clearer alternatives
- program_received_time_us() → recv_us()
- program_handle_time_consuming_us() → handle_us()
- instruction_outer_index() → outer_index()
- instruction_inner_index() → inner_index()
- Update all implementations across event parsers and processors

Improves developer experience while maintaining semantic clarity.
