[BUG] LSP (clangd) tool's workspaceSymbol operation can't pass a query string — schema is missing the parameter

What's Wrong?

▎ The LSP tool exposes a workspaceSymbol operation documented as "Search for symbols across the entire workspace", but the schema accepts only filePath, line, character
▎ (with additionalProperties: false). LSP's workspace/symbol request requires a query: string parameter — there's no way to pass it through the wrapper.
▎
▎ Behaviorally, the cursor line/character is completely ignored — output is byte-identical regardless of cursor position, returning ~100 alphabetical symbols (mostly
▎ stdlib / OpenCV / Eigen / gtest), hiding any user code symbols.
▎
▎ All other LSP operations (goToDefinition, findReferences, hover, documentSymbol, incomingCalls etc.) work as expected.
▎
▎ Suggested fix: add query: string to the schema for workspaceSymbol (and ideally make line/character optional for that operation since they have no role).

What Should Happen?

claude should be able to query (fuzzy search) clangd workspaceSymbol
