Create a function secret

Creates a new secret for a deployed function. Secrets are encrypted environment variables accessible in your function code:

• Cloudflare Workers: env.SECRET_NAME
• Supabase Functions: Deno.env.get('SECRET_NAME')

Note: Secret values are write-only and cannot be retrieved after creation.
