Replace browser tabs with Slack-style search

[adamleithp]

Problem

The browser-style tab strip makes the app chrome feel like a web browser instead of a focused workspace. A Slack-like global search gives the title bar a clearer primary action and faster access to commands, channels, and tasks.

Changes

• Replace the visible tab strip with a centered title-bar search trigger that opens the existing command menu.
• Keep persisted tab reconciliation mounted, while disabling tab-only keyboard shortcuts and controls.

How did you test this?

• pnpm exec biome check packages/ui/src/features/command/TitleBarSearch.tsx packages/ui/src/features/browser-tabs/BrowserTabStrip.tsx packages/ui/src/router/routes/__root.tsx
• pnpm build:deps
• pnpm --filter @posthog/ui typecheck
• pnpm --filter @posthog/ui test
