## Summary
The `connectSection` A/B experiment concluded as a true null (no effect
on activation or any downstream metric after 13 days at 50/50, ~153K
mature orgs). Saxon decided to ship the Connect section as the permanent
experience. This PR removes the Getting Started control variant, the old
Connect modal, all experiment flag gating, and related telemetry types.
## Changes
- Delete `GettingStarted/` directory (5 files: section component, types,
utils, progress hook)
- Delete old `Connect.tsx` dialog modal (replaced by ConnectSheet)
- Remove `connectSection` PostHog flag reads from `Home.tsx` and
`LayoutHeader.tsx`
- Remove `getSectionVisibility()` experiment logic and
`ConnectSectionVariant` type
- Remove `getting-started` from `DEFAULT_SECTION_ORDER`
- Always render `<ConnectSheet />` in header (no more conditional with
old `<Connect />` modal)
- Remove `variant` prop from `ConnectSection` component
- Remove 4 getting-started telemetry event interfaces from
`telemetry-constants.ts`
- Update `mergeSectionOrder` tests to reflect new section order
## Testing
Tested on Vercel preview:
- [x] Project homepage shows Connect section for new projects (< 10 days
old)
- [x] Connect section hidden for mature projects (> 10 days old)
- [x] Header Connect button opens ConnectSheet (not old modal)
- [x] Connect tiles open ConnectSheet with correct tab
- [x] Section drag-and-drop still works without getting-started in the
order
- [x] Existing users with `getting-started` in localStorage order don't
break (mergeSectionOrder strips it)

This PR moves several components which rely on `next` out of the `ui`
package to the `ui-patterns` package.
`ui-patterns` package is intented to be imported with specific imports
so it's ok if there are components reliant on `next` in there.
The `SonnerToaster` component has removed its dependency by requiring a
prop for `theme`.
