[Blueprints] Fix package typecheck target

[adamziel]

What it does

Makes playground-blueprints:typecheck typecheck the Blueprints package instead of packages/playground/remote.

Rationale

The target currently runs:

tsc -p packages/playground/remote/tsconfig.spec.json --noEmit
tsc -p packages/playground/remote/tsconfig.lib.json --noEmit

That means Blueprints changes can pass playground-blueprints:typecheck without checking Blueprints sources or specs.

Implementation

Points the target at:

tsc -p packages/playground/blueprints/tsconfig.spec.json --noEmit
tsc -p packages/playground/blueprints/tsconfig.lib.json --noEmit

The corrected spec typecheck exposed two deprecated-input tests that intentionally omit pluginData / themeData. Those tests now use @ts-expect-error because they verify runtime support for deprecated pluginZipFile and themeZipFile.

Testing instructions

npm run format:uncommitted
npm exec nx run playground-blueprints:typecheck
npm exec nx run playground-blueprints:lint
npm exec nx run playground-blueprints:test:vite -- --testFiles=packages/playground/blueprints/src/tests/steps/install-plugin.spec.ts
npm exec nx run playground-blueprints:test:vite -- --testFiles=packages/playground/blueprints/src/tests/steps/install-theme.spec.ts
git diff --check

Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

Fixes the playground-blueprints:typecheck Nx target so it checks the Blueprints package (not packages/playground/remote) and updates a couple of tests to account for deprecated-but-supported inputs now being caught by the corrected typecheck.

Changes:

• Update playground-blueprints:typecheck to run tsc against Blueprints’ tsconfig.spec.json and tsconfig.lib.json.
• Add @ts-expect-error annotations in two tests that intentionally use deprecated pluginZipFile / themeZipFile.
• Minor test formatting tweaks to toThrow(...) expectations.
