Replace common/*, browser/*, and headless/* path-mapped imports with relative paths across src/, addons/, test/, and demo/. Remove paths from all tsconfig.json files and include addon typings directly. Addon sources import shared code via out-esbuild/ so unit tests resolve compiled modules with runtime const enums. Fix benchmark bare imports and normalize corrupted tsconfig formatting. Resolves #5896 Co-authored-by: Daniel Imms <Tyriar@users.noreply.github.com>
