fix(pwsh): pin CI expectations for the mirror design

- jscpd: the executor/tool mirror dsh-bash-local/dsh-tool-bash by design
  (Agent Note), so the mirrored regions carry explicit ignore markers with
  reasons instead of being flagged as duplication.
- pwsh-local: a self-terminated process reports SIGTERM or SIGKILL on
  POSIX (PowerShell's Stop-Process choice), not only SIGTERM.
- gen-tool-catalog.spec: the shipped-tool completeness list gains 'pwsh'.
