chore(release): v0.21.0

[wmadden-electric]

Release v0.21.0. Merging this triggers the Publish to npm workflow.

Ships the local Postgres emulator fix from #298: @prisma/composer-prisma-cloud now declares and resolves its own @prisma/dev (^0.25.2), so messages over 64 KiB no longer crash prisma dev.

Change walkthrough

This is the v0.21.0 release PR: a mechanical monorepo-wide version bump from 0.20.0 to 0.21.0. Merging it triggers the Publish to npm workflow; the release ships the already-merged #298 fix that lets @prisma/composer-prisma-cloud resolve its own @prisma/dev ^0.25.2 so the local Postgres emulator no longer crashes on messages over 64 KiB.

Version bump mechanics. Every workspace package — the private framework packages, prisma-cloud lowering/shared-module packages, the public @prisma/composer and composer-cli packages, plus examples, the integration-test package, and the website — had its version field and all workspace: specifiers bumped in lockstep, with no 0.20.0 specifiers or versions remaining in any package.json. The regenerated pnpm-lock.yaml matches: importers now carry workspace:0.21.0 specifiers, and the composer-prisma-cloud importer resolves @prisma/dev to 0.25.2. External pins (@prisma/cli-engine 0.4.0, @prisma/orm-postgres 8.0.0-rc.11, alchemy, effect, etc.) are correctly untouched.

Release inputs. The root package.json version at line 51 is what the publish workflow's version-determination script reads, so it drives the npm release. The skill metadata library_version was bumped to match, which keeps the skill consistent with the published @prisma/composer version.

Deliberately unchanged 0.20.0 references. Several spots still mention 0.20.0 but refer to the buggy @prisma/dev 0.20.0 that alchemy's ^0.20.0 pin pulls in — e.g. the regression-test comment in postgres.test.ts, the postgres.ts docs, check-prisma-dev-pin.test.mjs, gotchas.md, and the skill body. These are historical bug documentation, not release versions, so leaving them alone is correct.

The change follows the repo's documented release procedure (scripts/bump-minor.ts → set-version.ts → lockfile regeneration).

Holding this release until #299 merges; the branch will be updated onto main afterwards so v0.21.0 includes it.
