feat: add experimental support for AST parsing and static graph indexing

- Introduced CLI options for using AST grep parsers and enabling static graph relationships during indexing.
- Updated configuration management to load new settings for AST parsing and static graph types.
- Enhanced AST grep processor to handle imports with aliases and improve relationship tracking.
- Modified TreeSitter parsers to support synthetic module scopes for better static graph persistence.
- Implemented global relationship updates in the incremental indexer for static graph expansion.
- Added new ArtifactTag and FloatingFileBrowser components to the frontend for improved terminal dashboard functionality.
- Created utility functions for detecting CCW artifacts in terminal output with associated tests.
