/**
 * CI-level safety net: every HanaAgent tool defined under lib/tools/ and

 * Static source scan (no engine boot). Handles both string-literal names
 * (`name: "x"`) and constant-reference names (`name: SOME_CONST`), where the
 * latter are resolved by looking up `export const SOME_CONST = "value"` in
 * the same directory.  (Source files are .ts after the JS → TS migration.)
