Response Notes

Returns a method signature with parameters. Fully qualified method names work when containingTypeName is omitted; a symbolKey selects a specific overload. If a key does not resolve, discover the method again with search_symbols or resolve_symbol. Results use top-level fields with success. Compact is the default; full adds responseDiagnostics. Both modes retain errors, coverage, partial state, and recovery advice.
