fix(client): address CI and review findings on blank-session reuse

- docs: fix cross-class note links (../feature/...), mirror the membership
  reuse criterion in README.zh.md and the connectWorkspace architecture
  note (EN/ZH/sidecars re-recorded)
- test(client): stray + member blank at the same path — the scan skips the
  stray and reuses the member
- test(web): re-registration after delete now mints a fresh blank session
  (the old cwd-only reuse is gone), so the account is no longer empty;
  assert the retained seeded session is still not re-adopted
