feat(01-03): templ layout/index/fragments + handlers + chi router
- templates/layout.templ: base HTML shell per UI-SPEC §Base Layout Contract
  (max-w-5xl container, slate-50 header, slate-200 borders, footer copy,
  /static/tailwind.css in <head>, /static/htmx.min.js deferred at body end —
  D-10: HTMX never loaded from a CDN)
- templates/index.templ: root page consuming @ui.Card and @ui.Button for the
  canonical HTMX demo (UI-SPEC §Component Library Contract canonical block)
- templates/fragments.templ: TimeFragment renders <span> with RFC3339 UTC
  timestamp; templ auto-escapes interpolation (T-01-13)
- internal/web/handlers.go: HealthzHandler (200 ok / 503 degraded per D-20,
  2s Ping timeout), IndexHandler, DemoTimeHandler with injected clock
- internal/web/router.go: Pinger interface; NewRouter wires
  RequestIDMiddleware → RealIP → SlogLoggerMiddleware → Recoverer (D-08
  + Pitfall 6 — chi middleware.Logger deliberately NOT registered) and
  routes /, /healthz, /demo/time, /static/* via http.FileServer (T-01-08
  path traversal blocked by http.Dir)

All six handler tests + ui package tests are GREEN under default go test.

// Library Contract / §HTMX Interaction Pattern). The demo CTA is rendered
