SPEC and README: owner rulings, issues 2 to 5, internet-ready defaults (closes #6)
Rewrite `SPEC.md` and `README.md` to the owner's rulings. The seven answers to the spec's questions now stand where their topics live, and the questions section is gone. Bans follow the owner's model: seven days for a clear sign of attack and permanent on any further request, an hour for a broken limit, tripled on a repeat within a day, permanent past seven days. The state files hold all state, are watched, and take in an admin's edits while running. Every ban carries notes, and each client's history survives a restart. Size and time limits apply in both directions. Only `UPSTREAM_URL` is required: the Core Rule Set refuses what it flags and every limit has a default. Model: opus-5-5
