feat(02-06): implement logout, protect GET /, and update layout with auth state
- Add LogoutHandler: deletes session row (D-06), clears cookie, redirects to /login
- Protect GET / inside RequireAuth group; remove old top-level registration
- Add POST /logout inside same RequireAuth group (D-22: POST-only logout)
- Update Layout signature to accept *auth.User; render logout form + email when authed
- Update Index template to accept *auth.User and show "Signed in as {email}"
- Update SignupPage/LoginPage to pass nil to Layout (auth pages are unauthed)
- Update IndexHandler to pull user from auth.Authed(ctx) and pass to template
- Update TestIndex_RendersHxGet -> TestIndex_UnauthRedirects (GET / now protected)
- AUTH-04 (logout) and AUTH-05 (protected /) are now closed

// Package templates owns the server-rendered HTML for the Phase 1 walking

// Layout is the base HTML shell every page renders inside. The structural
// classes, container width (max-w-5xl), horizontal padding, header strip,
// footer, and asset references (/static/tailwind.css, /static/htmx.min.js)
// are locked by UI-SPEC §Base Layout Contract and CONTEXT D-10 — do NOT
// load HTMX from a CDN.
//
// user is non-nil when the request context carries an authenticated session.
// When non-nil, the header renders a Log out POST form (D-22). Auth pages
// pass nil since they're gated behind RedirectIfAuthed and never shown to
// authed users.
