chore: delete redundant test archive - enforce zero redundancy policy

Deleted entire tests/archive/ directory (17+ test files, 188KB)
- All archive tests were 100% redundant with active tests
- Archive contained: toggles, zoom, hyperscript, keyboard, integration, misc tests
- Active tests (0-11) provide superior coverage

Updated TEST-SUMMARY.md:
- Removed archive references
- Added "Test Philosophy" section
- Updated test count to reflect deletion
- Emphasized zero redundancy policy

Coverage mapping (archive → active):
- toggles/* → 1-toggles.test.mjs ✅
- zoom/* → 0-zoom.test.mjs + 10-zoom-persistence + 11-zoom-ui-exclusion ✅
- hyperscript/* → 3-hyperscript.test.mjs + 9-hyperscript-def-limit ✅
- keyboard/* → 2-keyboard-shortcuts.test.mjs ✅
- integration/* → All active tests combined ✅
- misc/* → Various active tests ✅

Philosophy: If a test doesn't provide unique value, it doesn't exist.

+### 8-hover-sync.test.mjs
+**Purpose**: Hover state synchronization between UI elements
+- ✅ PDF button hover sync (action bar ↔ menu)
+- ✅ Print button hover sync (action bar ↔ menu)
+- ✅ Zoom control highlight on hover
+- ✅ No refresh required for hover effects

+### 9-hyperscript-def-limit.test.mjs
+**Purpose**: Verify NO 3-def limit with hyperscript 0.9.14+
+- ✅ Multiple def statements across multiple files
+- ✅ All hyperscript functions load correctly
+- ✅ Toggle functions work (toggleCVLength, toggleIcons, toggleTheme)
+- ✅ Hover sync functions work (syncPdfHover, syncPrintHover, highlightZoomControl)
+
+**Historical**: Proves hyperscript 0.9.14+ has no def limit
+
+**Run**: `bun tests/mjs/9-hyperscript-def-limit.test.mjs`
+
+### 10-zoom-persistence.test.mjs
+**Purpose**: Zoom level persistence across page reloads
+- ✅ Zoom saves to localStorage when changed
+- ✅ Zoom restores correctly on reload (e.g., 150%)
+- ✅ Reset to 100% works and persists
+- ✅ localStorage updates in real-time
+
+**Critical**: Fixed bug where zoom-control.html:10 set wrong element's value
+
+**Run**: `bun tests/mjs/10-zoom-persistence.test.mjs`
+
+### 11-zoom-ui-exclusion.test.mjs
+**Purpose**: Verify UI elements excluded from zoom
+- ✅ Footer outside zoom-wrapper (DOM structure)
+- ✅ Action bar outside zoom-wrapper
+- ✅ Menu outside zoom-wrapper
+- ✅ CV content inside zoom-wrapper
+- ✅ UI elements unchanged at 200% zoom
+- ✅ CV content properly zooms

+**Single Source of Truth**: The 12 tests in `tests/mjs/` (0-11) are the ONLY tests.
+- No archive, no legacy tests, no redundancy
+- Each test is systematic, comprehensive, and essential
