Subject: [PATCH] chore(js-client): upgrade to TypeScript 6

Bump typescript ^5.9.3 -> ^6.0.3 with a proper tsconfig migration so the
workspace compiles cleanly under TS 6 without ignoreDeprecations:

- Remove the deprecated `baseUrl` and rebase the `@leancodepl/pipe` path
  map to a relative specifier (TS resolves `paths` without `baseUrl`
  since 4.1).
- Migrate `moduleResolution` from the deprecated `"node"` to `"bundler"`
  (the pipe lib is bundled via rollup/swc), matching js_corelibrary's
  org-preferred setting. `module` stays `ESNext`.

Verified on Node 24.18: nx lint / build / test are green (the live
integration test only 403s on the sandbox egress block) and tsc reports
no TS5101 deprecation errors, with no ignoreDeprecations escape hatch.

Stacked on chore/js-client-npm-dependencies-bump (#92).
