This PR implements a performance optimization for the LSP linter by storing only LinterCodeAction objects in the cache instead of complete DiagnosticReport objects. This reduces memory usage since diagnostics are only needed when initially reported, while code actions are needed repeatedly for quick fixes and "fix all" operations.

Pull request overview

This PR implements a performance optimization for the LSP linter by storing only LinterCodeAction objects in the cache instead of complete DiagnosticReport objects. This reduces memory usage since diagnostics are only needed when initially reported, while code actions are needed repeatedly for quick fixes and "fix all" operations.

Key changes:

  • Changed storage from DiagnosticReport to LinterCodeAction in the cache
  • Added range field to LinterCodeAction struct to enable filtering without the full diagnostic
  • Updated iterator signatures from borrowed to owned parameters for better ergonomics

File Description
crates/oxc_language_server/src/linter/server_linter.rs Refactored cache from diagnostics: ConcurrentHashMap<String, Option<Vec<DiagnosticReport>>> to code_actions: ConcurrentHashMap<Uri, Option<Vec<LinterCodeAction>>>. Improved type safety by using Uri directly as key instead of String. Updated methods to extract and use only code actions.
crates/oxc_language_server/src/linter/error_with_position.rs Uncommented and activated the range field in LinterCodeAction struct, now including it when constructing instances.
crates/oxc_language_server/src/linter/code_actions.rs Changed function signatures from accepting borrowed iterators (Iterator<Item = &'a LinterCodeAction>) to owned iterators (Iterator<Item = LinterCodeAction>) for cleaner API and better ergonomics.

…te `DiagnosticReport` (oxc-project#16516)

> This PR implements a performance optimization for the LSP linter by storing only LinterCodeAction objects in the cache instead of complete DiagnosticReport objects. This reduces memory usage since diagnostics are only needed when initially reported, while code actions are needed repeatedly for quick fixes and "fix all" operations.
