Pull request overview

This PR reorganizes lambda-rs specifications and tutorials into feature-based subdirectories (rendering/audio/runtime) and updates indexes and references so navigation remains consistent after the move.

Changes:

• Update references in top-level docs (README.md, CONTRIBUTING.md) and spec template guidance (docs/specs/_spec-template.md) to reflect the new structure.
• Refresh last_updated metadata across moved/affected spec and tutorial documents.
