hemna aa43f60728 fix: add reset() to @singleton decorator to allow test isolation (#262)
The @singleton decorator stored its instance in wrapper_singleton.instance
inside a closure. Tests could reset __new__-based singletons via
ClassName._instance = None, but @singleton classes had no equivalent reset
mechanism, causing state to leak between tests.

Add wrapper_singleton.reset() to every @singleton-decorated class. The
method clears wrapper_singleton.instance so the next call creates a fresh
instance, matching the __new__ singleton pattern.

Update all tests to call ClassName.reset() instead of manually setting
ClassName.instance = None (tests/client/test_client.py x5,
tests/client/test_registry.py x1).

Tests added (tests/utils/test_utils.py):
- test_singleton_has_reset: asserts reset is callable on the wrapper
- test_singleton_reset_clears_instance: verifies a new instance is created
  after reset(), not the cached one
- test_singleton_instance_is_none_before_first_call: verifies the instance
  lifecycle — None → populated → None after reset

Closes #240
