Unify Tree-sitter implementation between CodeCharta and DependaCharta

[ChristianHuehn]

Feature request

Description

As a developer, I want a unified Tree-sitter implementation shared between CodeCharta and DependaCharta so that we can reduce duplication and maintain consistency across projects.

Acceptance criteria

• Common Tree-sitter parsing logic is extracted into a shared module/library
• Both CodeCharta and DependaCharta use the unified implementation
• All existing functionality is preserved
• Tests pass in both projects after migration
• Documentation explains the shared architecture

Assumptions & Exclusions

• Assumes CodeCharta and DependaCharta have similar Tree-sitter usage patterns
• May require coordination with CodeCharta team
• Could be published as a separate package or submodule

Development notes (optional Task Breakdown)

• Analyze current Tree-sitter implementations in both projects
• Identify common patterns and differences
• Design unified API/interface
• Extract shared code into common module
• Integrate unified implementation into DependaCharta
• Coordinate integration with CodeCharta team
• Add tests for the unified implementation
• Update documentation

Open questions

• Should this be a separate npm/Maven package or a shared submodule?
• What are the key differences in how each project uses Tree-sitter?
• Who will coordinate the CodeCharta side of the integration?
