The sanitizeSchemaForGoogle function was incorrectly stripping property
names like "pattern" and "format" from tool schemas because they matched
JSON Schema keywords in UNSUPPORTED_SCHEMA_FIELDS. This caused errors
like "required fields ['pattern'] are not defined in the schema properties"
when using tools like grep/find with Google's Cloud Code Assist API.
Modified the sanitization to track when processing inside a "properties"
object, only stripping schema keywords at the schema level, not when
they appear as property names.
