Code Review

This pull request replaces placeholder API keys in JULES_API.md and README.md with 'REDACTED_BY_JULES'. The reviewer recommends reverting these changes, as the original values were clear placeholders for users, and redacting them could lead to confusion.

Important

The original value "your-api-key-here" is a placeholder intended to guide users on where to insert their actual API key. Redacting it to 'REDACTED_BY_JULES' makes the documentation less clear and might confuse users into thinking this is a literal value or a system-defined keyword. Since this is not a real secret, it should not be redacted.

Suggested change

	export JULES_API_KEY='REDACTED_BY_JULES'
	export JULES_API_KEY="your-api-key-here"
