Add Ruby dual language server support with ruby-lsp as primary and Solargraph as experimental (#540)

* 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

   * **Rust now uses already installed rustup**: The rust-analyzer is no longer bundled with Serena. Instead, it uses the rust-analyzer from your Rust toolchain managed by rustup. This ensures compatibility with your Rust version and eliminates outdated bundled binaries.
   * **Kotlin now officially supported**: We now use the official Kotlin LS, tests run through and performance is good, even though the LS is in an early development stage. 
   * **Add support for Erlang** experimental, may hang or be slow, uses the recently archived [erlang_ls](https://github.com/erlang-ls/erlang_ls)
+  * **Ruby dual language server support**: Added ruby-lsp as the modern primary Ruby language server. Solargraph remains available as an experimental legacy option. ruby-lsp supports both .rb and .erb files, while Solargraph supports .rb files only.
 
 * Client support:
   * New mode `oaicompat-agent` and extensions in the openai tool compatibility, **permitting Serena to work with llama.cpp**
