Walk the whole tree once and collect `const IDENT = "value"` bindings so * later passes can resolve bare-identifier channel arguments. Only scalar * string literals are tracked — template literals and expressions are left * unresolved. This is a flat lookup; scope boundaries are ignored (a single * const table per file is sufficient for the common Socket.IO pattern). */
