refactor(build): extracted shared TypeScript config into tsconfig.base.json

- Created tsconfig.base.json with shared compilerOptions (ESNext, bundler resolution, strict mode, Bun types) and workspace path mappings for all packages.
- Updated root tsconfig.json and all package tsconfigs to extend the base config via `extends`, removing 50 lines of duplicated compiler options.
