Redeign tooltip for different intents usage

Description

Redesigns the tooltip system so behavior matches intent instead of using one global style everywhere.

Core changes (tooltip.tsx)

• Introduces two tooltip variants:
  • default — 300ms hover delay, fade/zoom animation. For informational content (truncated text, hints, reconnect messages, pin/unpin actions).
  • instant — 0ms delay, no animation. For navigation and layout controls where the tooltip is just a label (icon buttons, folded sidebar items, top bar actions).
• Removes per-tooltip nested TooltipProvider wrappers from TooltipSimple, so all tooltips share the app-level provider and the Radix “warm cursor” skip-delay window.
• Updates default provider timing from 100ms to 300ms for both delayDuration and skipDelayDuration.

Call-site updates (19 files)

• Applies variant="instant" to navigation/layout tooltips across the project sidebar, top bar, session panel, home hub toolbar, search input, triggers panel, and shadcn sidebar menu buttons.
• Keeps variant="default" (implicit) for informational tooltips such as agent names and reconnect hints.
• Removes ad-hoc delayDuration overrides where the new variants replace them.
• Removes the sidebar’s nested TooltipProvider delayDuration={0} in favor of explicit instant tooltips on collapsed menu items.

This makes icon-only controls feel snappy while preserving a calmer, animated experience for content-heavy tooltips.

• No frontend/UI changes in this PR.

Suggested manual checks:

1. Instant tooltips — Hover folded sidebar nav items, top bar icon buttons (support, settings, fold/expand), and home hub view toggles. Tooltips should appear immediately with no animation.
2. Default tooltips — Hover workforce agent cards (icon-only mode) and reconnect hints. Tooltips should appear after a short delay with fade/zoom animation.
3. Warm cursor — Move quickly between adjacent icon buttons; subsequent tooltips should open without re-waiting the full delay.
4. Collapsed sidebar — Confirm shadcn sidebar menu tooltips still show labels when collapsed.
