build(config): split tsconfig into IDE config and dedicated production compile

tsconfig.json now covers all src/ files (including __tests__ and __mocks__)
so the VS Code language service resolves @types/jest and stops reporting
errors in test files.

tsconfig.build.json extends tsconfig.json and re-adds the test exclusions,
keeping the production compile (tsc) free of test files.

tsconfig.test.json extends tsconfig.json and adds jest/node types for
ts-jest. jest.config.js wired to use it via globals["ts-jest"].tsconfig.

package.json: compile and watch:types scripts now target tsconfig.build.json.
