Hyena Dart v1.2.3

Fixed

• Normalize and absolutize analysis targets and discovered source paths before creating Dart analyzer contexts, including current-directory and trailing-separator inputs.
• Resolve only files that belong to the selected Dart analyzer context, preventing nested tool worktrees from crashing analysis without hard-coded tool-directory exclusions.

Verification

• 104 tests passed locally and on Ubuntu, macOS, and Windows.
• Lower-bound dependency analysis and CLI smoke tests passed.
• dart pub publish --dry-run completed with zero warnings.
