Support symfony/options-resolver 8 (fixes #290)

Nested-options-via-Closure passed to setDefaults() was deprecated in
options-resolver 7.3 and removed in 8.0, leaving the closures stored as
raw defaults and causing "Cannot use object of type Closure as array" in
Client::postResolve().

Bind each nested resolver explicitly via setOptions() when available,
falling back to the legacy closure-default pattern on older versions.
