Cookie opts structure + +**Decision**: Support the same options as Express's `res.cookie`: `domain`, `path`, `expires`, `httpOnly`, `maxAge`, `secure`, `sameSite`, `encode`. Accept either `maxAge` (ms from now) or `expires` (Date) for expiration. + +**Rationale**: Express-compatible API reduces the learning curve.

This matches Express behavior. +- [Breaking change to writeHead] Internal callers pass a headers object to `writeHead(res, headers)`.
