chore: remove superseded product code — repository is now the docs + issues front door

Removes, per maintainer confirmation (see previous commit):
- apps/objectos (@objectos/server — superseded by the official runtime
  image ghcr.io/objectstack-ai/objectstack)
- apps/objectos-one (ObjectOS One — discontinued; demos/evals are served
  by the Docker image and ObjectOS Cloud trials)
- packages/, docker/, helm/, e2e/, examples/, scripts/
- workflows: docker.yml, one.yml, release-one.yml

Kept: apps/docs + content/ (docs.objectos.ai source), LICENSE, NOTICE,
TRADEMARK.md, CHANGELOG.md. ci.yml trimmed to the docs-only workspace;
package.json scripts and pnpm-workspace.yaml pruned; lockfile
regenerated.

All previously released source remains Apache-2.0 in git history —
maintainers should place an 'archive/apache-final' tag on the pre-merge
main before merging.
