chore(stop,resume): drop what Issue #63 left unused (Issue #63)

- workspace_uuid.py: the unused sys import.
- stop_session.sh: the orphan CAPTURE_ID and the blank padding that kept
  later line numbers; the inventory pins follow the move instead.
- lib.sh: capture_conversation_id, which nothing calls any more.
- resume SKILL.md: the flow names the session-id decision (session_ids.py),
  not resolve_session_id.sh.

-`resume_session.sh` does the whole flow: original-cwd check, control-plane binding, session-id resolution (`resolve_session_id.sh`), the herdr-alive check, the agent command (adapter `resume-spec`, or `spawn-spec` for a Class A fresh spawn), spawn (just before it, the session's own empty shell left by a server restart is closed: same session id, no agent, nothing running; `lib_py/herdr_restore.py`), start-up dialogs, and the YAML update (`update_yaml_resumed.sh`, which also publishes a `progress "resumed"` event when the row has a `delegate_job_id`). It never attaches; attaching is a separate step that names the server, because the server the script exports does not reach the calling shell and the native `herdr` binary does not route on environment variables: `herdr --session <server> agent attach <name>` (`<server>` = the `--herdr-session` you passed, or the row's `herdr_session`).
