langchain-profiles refresh corrupts strings containing JSON literal substrings
`langchain-model-profiles` CLI `refresh` performs global string replacements (`true`->`True`, `false`->`False`, `null`->`None`) on a `json.dumps` result, corrupting quoted JSON keys and values that contain those substrings. The generated `_profiles.py` still imports successfully but with silently altered profile data.
