Add morning briefing, command palette, and boot animations

#11 Smart Morning Briefing: auto-speaks once per day before noon — fetches
tasks, appointments, active alerts, and weather, composes a ~2-sentence TTS
summary. Stored in localStorage (jarvis_brief_YYYY-MM-DD) to fire only once.

#12 Quick Command Palette (Ctrl+K): frosted-glass overlay with 20 pre-loaded
commands across 6 groups (Network/Agents/Planner/Media/Smart Home/System).
Fuzzy filter as you type, arrow-key navigation, Enter to fire. Matches are
highlighted. Backdrop click or Escape to close.

#13 Live Boot Animation: stat bars and numbers now count from 0 on first render
via tickTo() change. Arc Reactor rings spin in with staggered delays (0.08s
per ring) on login using boot-spin CSS class + @keyframes arcBootSpin.
