chore: type-check tests following Effect v4 pattern

[solidsnakedev]

Summary

Adopt the Effect v4 tsconfig structure so that pnpm check type-checks both source and test files in one pass.

What changed

• Root tsconfig.json — references tsconfig.build.json (src only) and directly includes all packages/*/test/**/*.ts globs with path aliases + noEmit: true
• Root tsconfig.build.json — now references all 4 package build configs (previously only evolution)
• Root package.json — added "check": "tsc -b tsconfig.json" for centralized type-checking
• Per-package tsconfig.json — evolution and evolution-devnet now reference their tsconfig.test.json (aiken-uplc and scalus-uplc already did)
• Per-package scripts — type-check changed from tsc --noEmit (which checked zero files in a project-reference monorepo) to tsc -b tsconfig.json

Why

tsc --noEmit in a monorepo with project references and "include": [] checks zero files. Tests have never been type-checked. This PR surfaces ~108 pre-existing type errors in test files that were previously invisible.

Effect v4 pattern

Layer	Config	Purpose
Build	tsconfig.build.json → per-package tsconfig.build.json	tsc -b for emitting dist
Check	tsconfig.json → refs build + includes test globs	tsc -b for full type-checking

The pre-existing test type errors are not fixed in this PR — they will be addressed separately.

Pull request overview

Aligns the repo’s TypeScript project-reference setup with the Effect v4 pattern so a single root build (tsc -b) can type-check both sources and tests.

Changes:

• Updated root tsconfig.json to reference tsconfig.build.json and include packages/*/test/** globs with path aliases and noEmit.
• Expanded root tsconfig.build.json to reference all package build configs.
• Added centralized check scripts (root + packages) and switched per-package type-check to tsc -b tsconfig.json.
