* Introduce SymbolBody representation (compact), from which the
body can be reconstructed, rendering body computation lazy
* Introduce SymbolBodyFactory for the creation of such instances,
ensuring that instances created from the same factory share
the same file content, allowing the in-memory and on-disk caches
to have a significantly smaller memory footprint
* Change type of "body" key in UnifiedSymbolRepresentation to use
SymbolBody instead of str
* Adjust all usages of the "body" key
* Implement Ruby dual language server support with ruby-lsp and Solargraph
- Add ruby-lsp as primary Ruby language server with modern LSP features
- Mark Solargraph as experimental legacy option (ruby_solargraph enum)
- Implement Bundler-first installation strategy for ruby-lsp
- Add Rails project detection and performance optimizations
- Fix LSP protocol compliance for Solargraph (languageId: "ruby")
- Support both .rb and .erb files for ruby-lsp, .rb only for Solargraph
- Address reviewer feedback on dependency management and error handling
- Update test compatibility for dual language server behavior
