feat(gui): profile switcher chip in header

Visible visual indicator of the active profile + click-to-swap dropdown.
Closes the last small UX gap pointed out in earlier sessions.

Tauri (crates/jarvis-gui/src/tauri_commands/profile.rs)
  - profile_list()   → Vec<String> of available profile names
  - profile_active() → {name, description, icon, greeting}
  - profile_set(name) → swaps active profile, returns new active

Frontend (frontend/src/components/Header.svelte)
  - Polls profile_active every 5 seconds.
  - Shows a coloured chip with icon+name when profile != "default"
    (orange tint, attention-grabbing). For "default" — muted star chip.
  - Click opens a dropdown listing all profile names; click one → swap.
  - Dropdown closes on outside-click (shared handler with lang dropdown).
  - SCSS styled to match existing aesthetic.

Build: cargo build --release -p jarvis-gui green (2m).

Now the user can see at a glance which profile is active (e.g. "💼 work")
without having to ask voice or open Settings.
