## What
When an app is built (`twenty build` / `twenty publish`), the SDK now
generates a marketplace cover image and sets it as the app's screenshot,
but only when the app declares a `logoUrl` and has no `screenshots`. The
cover composites the app's logo and the Twenty logo over the branded
halftone backdrop, matching the design reference.
## Why
Most apps ship a logo but no screenshots, so their marketplace detail
page had no hero visual. This gives them a polished cover for free, with
no per-app design work.
## Notes for reviewers
- Generation lives in the build path (`operations/build.ts`), not
`buildManifest`, so `twenty dev` and the shared manifest builder are
untouched. It is best-effort: on failure it logs a warning and the build
continues.
- The cover is written to `.twenty/output` and registered as a public
asset + screenshot, so the existing copy/checksum/serve pipeline handles
it unchanged. No app source files are modified.
- Adds `sharp` as a runtime dependency of `twenty-sdk` (a build-time
tool, like `esbuild`); it is not bundled into built apps.
