fix(app): emit declaration files and fix package type exports for external consumers (#26)

* fix(app): emit declaration files and fix package type exports for external consumers

- Add tsconfig.build.json that emits .d.ts only from src/ (excludes examples with test fixture imports)
- Change build script to vite build && tsc -p tsconfig.build.json so declarations survive Vite's dist clean
- Point exports.types from ./src/index.ts to ./dist/index.d.ts so consumers get compiled declarations
- Remove src/ from published files — only dist/ is shipped
- Add tests/consumer/ fixture with strict tsconfig and proof-obligation import to pass tsc --noEmit

Closes #25

* fix(tests): remove void operator from consumer fixture (sonarjs/void-use)

* fix(tsconfig): exclude tests/consumer from main typecheck

tests/consumer has its own tsconfig.json with paths mapping for
@prover-coder-ai/openapi-effect. Including it in the main tsc --noEmit
causes TS2307 since the package isn't resolved in the monorepo context.

* fix(consumer): address CodeRabbit review — build before consumer check, add baseUrl

- test:consumer now runs tsc -p tsconfig.build.json first so the script
  works on a clean checkout without a pre-built dist/
- Add baseUrl: "." to tests/consumer/tsconfig.json alongside paths so
  TypeScript module resolution follows the standard paths protocol
