chore(yarn): Fix build after yarn 4.14.1 upgrade

[Tobbe]

#1673 disables build scripts for packages by default. I added overrides for packages we need to build for Cedar apps, but didn't realize I needed to add them for the framework itself too. This PR addresses that oversight.

Greptile Summary

This PR adds a dependenciesMeta block to the root package.json to re-enable install/build scripts for native and binary packages after Yarn 4.14.1 began silently disabling them by default. It is the framework-side counterpart to the per-project fix landed in #1673.

• Eight packages are opted back in with \"built\": true: @prisma/engines, @swc/core, better-sqlite3, cypress, esbuild, lefthook, msw, and prisma.
• The documentation in docs/implementation-docs/2026-03-26-cedarjs-project-overview.md remains factually accurate — it refers to "Yarn 4" and "Nx build orchestration," both still correct at yarn@4.14.1.

Confidence Score: 4/5

Safe to merge; the change is minimal and targeted, with a single question about whether @playwright/test needs to be included.

The change correctly mirrors the approach used for user-facing project fixtures in #1673. The only open question is whether @playwright/test should be opted in; its absence is fine if CI invokes playwright install independently, but could silently break browser-based tests otherwise.

Only package.json changed; verify whether @playwright/test install scripts run via a separate CI step before merging.

Important Files Changed

Filename	Overview
package.json	Adds dependenciesMeta block re-enabling build scripts for 8 native/binary packages after Yarn 4.14.1 began disabling install scripts by default; @playwright/test is absent from the opt-in list and may need to be included depending on how CI installs browser binaries.
