## Motivation
CPP tests in dispatcher were failing due to a mismatch in registry key
and string representation.
## Technical Details
Bug 1 - Registry key mismatch: The registry stored kernels using
get_name() but lookups used encode_identifier(), causing all registry
lookups to fail. Fixed by changing registry.cpp:58 to use
encode_identifier() for storage.
Bug 2 - String representation changes: Tests checked for
"persist"/"nopers" substrings, but the code emits "True"/"False". Fixed
by replacing brittle substring checks with comparison-based assertions
in test_kernel_key.cpp and test_kernel_key_extended.cpp.
## Test Plan
Tested with CPP tests in dispatcher
## Test Result
Validation: All three core cpp tests now pass:
- test_kernel_key - 6/6 tests passing
- test_kernel_key_extended - 25/25 tests passing
- test_registry - 8/8 tests passing
