fix(hindsight): use configured timeout in _run_sync for all async operations

The previous commit added HINDSIGHT_TIMEOUT as a configurable env var,
but _run_sync still used the hardcoded _DEFAULT_TIMEOUT (120s). All
async operations (recall, retain, reflect, aclose) now go through an
instance method that uses self._timeout, so the configured value is
actually applied.

Also: added backward-compatible alias comment for the module-level
function.
