fix(seedgo): CWD-first _find_registry() in 3 handlers

bypass_handler.py, diagnostics/discovery.py, readme_ops.py all walked
from __file__ only — finds AIPass registry even when CWD is an external
project. Now follows audit/discovery.py pattern: CWD parents first,
__file__ fallback, *_REGISTRY.json glob instead of hardcoded name.
Removed module-level REGISTRY_PATH caching from bypass_handler and
readme_ops (lazy call instead).
