Pamela ChiaandAli Waseem 578a73f966 feat(studio): connectSection experiment — replace Getting Started with Connect section (#43629) ...

## Summary

Re-ports PR #43119 against the current `ProjectHome` codebase (the
original PR targeted `HomeNew/` which was removed during the `homeNew`
graduation in #43437). Also unifies the `connectSheet` and
`connectSection` feature flags into a single `connectSection` flag — the
`connectSheet` flag is removed entirely, so both the ConnectSheet
(header) and ConnectSection (homepage row) are controlled by one
experiment.

- Adds `connectSection` PostHog experiment flag that controls two
things:
1. Swaps the Getting Started section for a Connect section on the
project homepage for new projects (< 10 days old)
2. Swaps the legacy Connect dialog for the new ConnectSheet panel in the
header
- **Control** (`getting-started`): existing Getting Started section +
legacy Connect dialog in header
- **Treatment** (`connect`): new 4-tile Connect section + ConnectSheet
in header
- `undefined` (loading): neither section renders, avoiding flash
- Tiles filtered by the same `useIsFeatureEnabled` flags as ConnectSheet
(`show_app_frameworks`, `show_mobile_frameworks`, `show_orms`)
- Connect tile clicks tracked via `home_connect_action_clicked`; section
render tracked via `home_connect_section_exposed`; sheet opens tracked
via `connect_sheet_opened` with source attribution (`header_button` or
`connect_section`)

## Changes

- `packages/common/telemetry-constants.ts` — new
`home_connect_section_exposed`, `home_connect_action_clicked`, and
`connect_sheet_opened` event types
- `ConnectSheet/ConnectSheet.tsx` — read `connectTab` query param and
sync to active mode on open; `handleModeChange` keeps param in sync on
tab switch; fire `connect_sheet_opened` event with source attribution on
open
- `ConnectButton/ConnectButton.tsx` — set `connectSource=header_button`
query param on click
- `ProjectHome/ConnectSection.tsx` — new component (4-tile connect
card); set `connectSource=connect_section` on tile click
- `ProjectHome/Home.tsx` — experiment flag wiring
- `LayoutHeader/LayoutHeader.tsx` — read `connectSection` flag instead
of `connectSheet` to toggle ConnectSheet vs legacy Connect dialog

## Test plan

To test on the Vercel preview, set `connectSection=connect` to 100% in
PostHog (or override via cookie `ph_override_connectSection=connect`).
No separate `connectSheet` flag is needed — `connectSection` controls
both features.
- [x] Treatment (`connect` variant) — "Get connected" section renders on
new project, Getting Started hidden
- [x] Control (`getting-started`) — Getting Started renders, Connect
section hidden
- [x] Mature project (> 10 days) — neither section regardless of flag
- [x] Clicking each tile opens ConnectSheet on the correct tab
(Framework / Direct / ORM / MCP)
- [x] Switching tabs inside sheet updates `connectTab` URL param
- [x] Closing sheet clears `connectTab` param
- [x] Direct URL deep-link (`?showConnect=true&connectTab=orm`) opens
sheet on correct tab
- [x] Dark mode — background gradient renders correctly
- [x] Light mode — background switches to light gradient
- [x] Responsive layout — 4 cols (xl), 2×2 (md), stacked (mobile)
- [x] Telemetry — `home_connect_section_exposed` fires once on load;
`home_connect_action_clicked` fires with correct `mode`
- [x] Treatment — header Connect button opens ConnectSheet (not legacy
Connect dialog)
- [x] Control — header Connect button opens legacy Connect dialog (not
ConnectSheet)
- [x] Telemetry — clicking a ConnectSection tile fires
`connect_sheet_opened` with `source: 'connect_section'`
- [x] Telemetry — clicking header Connect button fires
`connect_sheet_opened` with `source: 'header_button'`
