v0.0.9

Performance Improvements

• Visible range scanning: only processes visible lines instead of the entire document, significantly improving performance on large files.
• Debounced updates: added 100ms debounce to decoration updates to prevent excessive processing during rapid typing.

Bug Fixes

• Proper cleanup on deactivation: decoration types are now registered with context.subscriptions for automatic disposal when the extension deactivates.

Build & Development

• Docker support: added Dockerfile and Makefile for building the extension without requiring local Node.js/npm installation.
• Updated .gitignore: added shell and tool config files.

Documentation

• Improved README.md: added features section, supported patterns table, requirements, build instructions, and license info.
• Updated screenshot.
