build: typescript changes

- avoid patched typescript for typescript-transform-paths
- use `package.json#imports` subpath imports instead of `tsconfig#compileroptions.paths` path aliases
- use "solution-style" tsconfig with tsc build mode
- use exact paths for module specifiers everywhere
- upgrade `@typescript-eslint/*` to latest
- upgrade `eslint-plugin-n` to latest

 - Follow Conventional Commits as seen in history (`chore:`, `fix(scope):`, `ci:`, `refactor:`); include scope when useful.
 - Add a Changeset (`pnpm changeset`) for user-facing package changes; omit for tooling-only tweaks unless publishing impact.
 - PRs should describe intent, affected packages, and commands run (`build`, `lint`, relevant tests); link issues and include screenshots/logs for UX/CLI changes when helpful.
-- Avoid updating the TypeScript patch manually; use `pnpm run create-pnpm-patch-via-ts-patch` when bumping versions and keep `patches/typescript@...` in sync.
