docs(repo): studio is the 2.x line, ready to be the default branch

The repository now describes the two lines the version roadmap announced
(discussions/10748): 2.x on studio, 1.x on main-v2 in maintenance.

- README (en, zh-CN): a Versions section and a Studio 2.x release badge.
  Install leads with Reasonix Studio 2.x from the studio-v* pre-releases,
  with the 1.x CLI and desktop app beside it as the stable line. The
  zh-CN build-from-source section gains the Studio build it lacked.
- Issue forms offer 2.x / 1.x / 0.x, and the labeler maps them to v3 /
  v2 / v1, with the pasted version still overriding the dropdown. The
  forms link the roadmap. The PR template and CONTRIBUTING say which
  branch takes which changes.

Issue forms, schedules and Dependabot are read from the default branch
only, so these take effect when studio becomes it:
- CodeQL scans pushes and PRs on both lines, and the weekly scan checks
  out each line and files results under its own ref, so 1.x keeps its
  security scanning.
- v1-maintenance-schedule starts main-v2's nightly app-memory and
  diagnostic-overhead monitors, which measure the 1.x desktop app, on
  main-v2.
- Dependabot drops /desktop/frontend and /site, which do not exist on
  studio, and covers /desktop/frontend-next and /desktop/electron. It
  also names main-v2 as a target for patch updates only.

+1.x 中有价值的修复、测试和行为会逐项 review，适合新架构的会迁移或重新实现到 2.x。
