Privacy defaults

Every site gets an unguessable https://stacktr.ee/p/{token}/ URL. Pass public_slug to opt into https://{slug}.stacktr.ee/.

pii_check defaults to warn — common secrets and PII shapes (emails, SSNs, credit cards, OpenAI/GitHub/Stripe API key prefixes) are flagged in the response. Pass block to refuse uploads that match.
