v0.2.1-beta

• Refined parser migration toward explicit MapEvalConfig propagation
  • Migrated trace parsers to consume ParseContext instead of raw map where applicable
  • Removed implicit default-config translation paths from most trace parsing flows
  • Reused shared helpers like parse_marker() and parse_color_bar() to reduce duplicated translation logic
• Slimmed trace registry dispatch in trace_registry.rs
  • Removed registry-side .map(into_trace) adaptation
  • Moved trait-object conversion boundaries down into parser modules via *_trace() entrypoints
• Updated tests to validate the migration path remains stable
