chore: publish libpkgx to JSR as @pkgx/libpkgx

deno.land/x is read-only; new versions go to JSR.

- deno.json: name, version 0.23.0, exports (mod + deep paths brewkit needs)
- deps: npm:is-what@4.1.15, npm:outdent@0.8.0 (no deno.land/x deps)
- CI: publish-jsr.yml on release (OIDC)
- README: JSR import example
