 * Coverage focus matches docs/PLAN_PHP_LSP_INTEGRATION.md §9.1:
 *   - Param type binding (incl. arrow-function and anonymous closures)
 *   - Method call dispatch on typed receivers
 *   - Static call dispatch (Class::m, self::, parent::, static::)
 *   - new Class chains
 *   - Namespace + `use` clause resolution
 *   - Catch-clause exception type binding
 *   - PHPDoc @param / @var fallback
 *   - Magic-method (__call, __callStatic) emission
 *   - "Unindexed receiver" fallback (vendor types)
 *
 * Specific regression: (Prompt $p) => $p->value() must NOT route to a
 * global helpers.value function — see docs/PHP_LSP_PRE_FLIGHT.md §4.2.
