 * `cache` (added in 3.172.0, cognium-dev#254 T2-A): when provided, top-level
 * `findNodes` walks for function/method containers are replaced with O(1)
 * cache lookups populated by `collectAllNodes` at analyzer entry. Java's
 * `method_declaration`/`import_declaration` and JS's `function_declaration`/
 * `arrow_function`/`method_definition` are already in the language-cache set;
 * `constructor_declaration`, `function`, `function_expression` are added by
 * this ship. Falls back to `findNodes` when cache is absent (test / library
 * callers that build a Tree directly).
