275-290:⚠️ Potential issue | 🟠 MajorPropagate deprecation when bundled overloads are merged
On Line 275, tags are set only when a new overload bucket is inserted. In the merge path (Lines 284-290), if a deprecated overload is encountered after a non-deprecated one, the bundled item can incorrectly miss

Verify each finding against the current code and only fix it if needed. In `@src/feature/code_completion.cpp` around lines 275 - 290, When merging into an existing overload bucket (the branch that updates existing = overloads[it->second]), ensure deprecation is propagated: if the incoming overload's is_deprecated (or item.tags contains protocol::CompletionItemTag::Deprecated) is true then add protocol::CompletionItemTag::Deprecated to existing.item.tags (or set existing.item.tags = std::vector{...} if empty) so a later-deprecated overload won't lose the Deprecated tag; also keep the existing score/count/update logic (existing.count, existing.score, existing.item.sort_text) unchanged.

Check CXAvailability_Deprecated on CodeCompletionResult and set CompletionItemTag::Deprecated on the CompletionItem. Editors render this as a strikethrough on the completion label. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
