Reposition repository as the ObjectOS product front door (docs + issues); remove superseded product code (#38)

* docs: reposition this repository as the ObjectOS product front door

ObjectOS is now exclusively the commercial runtime environment for
ObjectStack applications (Cloud & Enterprise). This public repository
becomes its front door: the docs site (docs.objectos.ai), the issue
tracker, and the trademark policy.

- README: commercial positioning, editions table, pointer to the
  open-source ObjectStack framework (os start / official image) for
  self-hosting your own apps, and a 'what happened to the code here'
  section: @objectos/server superseded by the official runtime image;
  ObjectOS One discontinued (Docker image + Cloud trials cover
  demos/evals); all historical releases remain Apache-2.0 in git
  history.
- CONTRIBUTING: scope narrowed to docs + issues.
- AGENTS: repository description updated.

Confirmed by maintainer: 确认执行 A+B,停更 One。

* chore: remove superseded product code — repository is now the docs + issues front door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- apps/objectos (@objectos/server — superseded by the official runtime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.

* fix(docs): remove the ObjectOS One download surface from the docs site

apps/docs imported apps/objectos-one/package.json for the user-visible
version (lib/version.ts), breaking type-check after One's removal.
One is discontinued, so the whole download surface goes with it:

- app/[lang]/download page, components/download/*, lib/download-i18n.ts,
  lib/version.ts (no importers remain)
- nav: drop the Download item across all 7 locales (layout.shared.tsx)
- sitemap: drop the download entry

Verified locally: turbo type-check + build + test all green on the
docs-only workspace.
