feat: final production polish — light mode rebuild, lt.init(), cross-tab theme

Light mode — complete rebuild (section 51):
- Full token override for every surface, component, and state
- Desaturated accents: orange #c44e00, cyan #0062b8, green #006d35 etc.
- Glows replaced with subtle drop-shadow rings (no neon on white)
- Covers: toasts, modals, dropdowns, notification panel, context menu,
  right drawer, combobox, typeahead, wizard, timeline, pagination, tabs,
  badges, tables, code blocks, skeleton, avatar, sortable, markdown,
  scrollbars, buttons, nav drawer, WS status — nothing missed
- Dot-grid: neutral gray (was incorrect blue tint)
- Toast background uses var(--bg-overlay) instead of hardcoded dark rgba

Theme system improvements:
- _applyTheme now sets document.documentElement.style.colorScheme
- theme-color meta tag syncs on toggle (browser chrome follows theme)
- Cross-tab sync via storage event (toggle in one tab updates others)

lt.init() master initializer:
- Single call wires accordion, tooltip, alerts, clipboard, sidebar,
  submenus, and boot sequence
- Replaces 6+ individual .init() calls in user code
- demo HTML updated to use lt.init({ bootName: 'MY APP' })

Accessibility:
- Ticket table: add <caption class="lt-sr-only"> for WCAG compliance
- Table gets aria-label attribute
