chore: v2.8.74 — a member's chat no longer lags a turn behind the terminal

- Under server mode with per-user accounts, a member's Claude session chat
  showed the transcript as of the last import snapshot: transcript lookups
  used access(2), which cannot see past the member's 0700 projects folder.
  They now use stat, so the chat reads the live transcript again.
