feat: add 10 missing icon SVG paths, fix demo ESM imports, Lighthouse audit fixes

- Add SVG paths for: alt_route, animation, confirmation_number, devices,
  filter_center_focus, image, login, repeat, timer, verified
- Fix ISSUE-6: use ESM import from dist bundle instead of window.AgentUI
- Fix CLS on dividers, color contrast, ARIA labels, robots.txt SEO
- Add new structural directive components (au-if, au-repeat, au-show,
  au-portal, au-intersection, au-media, au-transition, au-timer)
- All paths sourced from official Google Material Design Icons repo
- Lighthouse: Performance 91, Accessibility 100, CLS 0

v0.1.151

+### au-show (Show/Hide with State Preservation)
+```html
+<au-show id="panel" condition>
+    <form>
+        <!-- Form values, scroll position, timers all survive toggle -->
+        <au-input label="Name" value="Alice"></au-input>
+    </form>
+</au-show>
+
+<script type="module">
+const panel = document.getElementById('panel');
+panel.condition = false; // hidden via display:none, stays in DOM
+panel.condition = true;  // visible again, all state intact
+
+panel.addEventListener('au-show', () => console.log('Visible'));
+panel.addEventListener('au-hide', () => console.log('Hidden'));
+</script>
+```
+
+**Key points:**
+- Children hidden with `display: none` — **not removed** from DOM
+- Internal state (form values, event listeners, timers) **preserved**
+- Use `au-if` when you want true DOM removal; `au-show` when toggling frequently
+- `display: contents` — zero layout impact
+
+### au-portal (DOM Teleportation)
+```html
+<!-- Source: portal lives here but children render elsewhere -->
+<div style="overflow: hidden;">
+    <au-portal target="#modal-container">
+        <au-modal open title="Escaped!">
+            <p>This modal is not clipped by overflow:hidden</p>
+        </au-modal>
+    </au-portal>
+</div>
+
+<!-- Target: teleported content appears here -->
+<div id="modal-container"></div>
+
+<script type="module">
+const portal = document.querySelector('au-portal');
+portal.addEventListener('au-teleport', () => console.log('Moved'));
+portal.addEventListener('au-return', () => console.log('Returned'));
+// Children auto-return on disconnect (cleanup)
+</script>
+```
+
+**Key points:**
+- Children are **moved** (not cloned) — DOM identity preserved
+- Solves `overflow: hidden` and z-index stacking context issues
+- Auto-cleanup: children return to source on disconnect
+- `target` defaults to `document.body` when absent
+
+### au-intersection (Viewport Observer)
+```html
+<!-- Lazy-load pattern -->
+<au-intersection once threshold="0.1">
+    <img data-src="hero.webp" alt="Hero" />
+</au-intersection>
+
+<script type="module">
+document.querySelectorAll('au-intersection').forEach(el => {
+    el.addEventListener('au-visible', (e) => {
+        console.log('Ratio:', e.detail.ratio);
+        const img = el.querySelector('img[data-src]');
+        if (img) { img.src = img.dataset.src; }
+    });
+    el.addEventListener('au-hidden', () => {
+        console.log('Left viewport');
+    });
+});
+</script>
+```
+
+**Key points:**
+- Declarative `IntersectionObserver` — no manual setup/cleanup
+- `once` mode disconnects after first intersection (lazy-load)
+- `threshold` (0–1) controls visibility ratio trigger
+- `root-margin` extends the viewport bounds (e.g. `"200px"` for preloading)
+- Read `el.isVisible` for current state
+
+### au-media (Responsive Rendering)
+```html
+<!-- Desktop-only sidebar -->
+<au-media query="(min-width: 768px)">
+    <aside class="sidebar"><nav>...</nav></aside>
+</au-media>
+
+<!-- Mobile-only bottom nav -->
+<au-media query="(max-width: 767px)">
+    <au-bottom-nav>
+        <au-nav-item icon="home">Home</au-nav-item>
+    </au-bottom-nav>
+</au-media>
+
+<script type="module">
+const media = document.querySelector('au-media');
+console.log(media.matches); // true/false
+media.addEventListener('au-match', () => console.log('Query matches'));
+media.addEventListener('au-unmatch', () => console.log('Query no longer matches'));
+</script>
+```
+
+**Key points:**
+- Children **truly removed** from DOM when query doesn't match (like `au-if`)
+- Same DOM nodes restored on match (identity preserved)
+- More efficient than CSS `display: none` for heavy components
+- Read `el.matches` for current state
+
+### au-transition (Enter/Leave Animations)
+```html
+<style>
+    .fade-enter-active, .fade-leave-active { transition: opacity 0.3s ease; }
+    .fade-enter-from, .fade-leave-active { opacity: 0; }
+</style>
+
+<au-transition name="fade" active>
+    <div>I animate in and out!</div>
+</au-transition>
+
+<script type="module">
+const transition = document.querySelector('au-transition');
+transition.active = true;  // applies fade-enter-from → fade-enter-active
+transition.active = false; // applies fade-leave-from → fade-leave-active
+
+transition.addEventListener('au-enter', () => console.log('Enter started'));
+transition.addEventListener('au-leave', () => console.log('Leave started'));
+</script>
+```
+
+**Key points:**
+- Vue-inspired class naming: `{name}-enter-from`, `{name}-enter-active`, `{name}-leave-from`, `{name}-leave-active`
+- Does **not** define visual CSS — you provide the transition styles
+- `name` attribute sets the class prefix (default: `au`)
+- `display: contents` — zero layout impact
+
+### au-timer (Declarative Timer)
+```html
+<!-- Count-up timer -->
+<au-timer id="stopwatch" interval="1000" autostart></au-timer>
+
+<!-- Countdown timer (30 seconds) -->
+<au-timer id="countdown" interval="1000" countdown="30"></au-timer>
+
+<script type="module">
+const timer = document.getElementById('stopwatch');
+timer.addEventListener('au-tick', (e) => {
+    display.textContent = e.detail.count; // 1, 2, 3...
+});
+timer.start();
+timer.stop();
+timer.reset();
+
+const countdown = document.getElementById('countdown');
+countdown.addEventListener('au-tick', (e) => {
+    display.textContent = e.detail.count; // 30, 29, 28...
+});
+countdown.addEventListener('au-complete', () => {
+    showToast('Time is up!', { severity: 'warning' });
+});
+countdown.start();
+</script>
+```
+
+**Key points:**
+- Automatic `clearInterval` on disconnect — no memory leaks
+- `countdown` attribute enables count-down mode (fires `au-complete` at 0)
+- `autostart` starts timer on connect
+- Interval clamped to ≥100ms for safety
+- Read `el.count` and `el.running` for current state
