ReSoul

Reset the workspace bootstrap state so the next fresh session can start from the official upstream BOOTSTRAP.md.

Primary workflow

Warn that running resoul will fetch the official BOOTSTRAP.md, then archive the current SOUL.md, USER.md, and IDENTITY.md into .trash/ and remove them from the workspace root if they exist.
Require an explicit second confirmation before executing anything. Do not treat vague replies like "ok" or "继续" as sufficient; require a clear confirmation that the user agrees to archive and remove the current SOUL.md, USER.md, and IDENTITY.md from the workspace root.
Fetch the latest official upstream template to a temporary file first, and only continue if the fetch succeeds.
Archive the current SOUL.md, USER.md, and IDENTITY.md into .trash/ if they exist.
Write the fetched template to the workspace root as BOOTSTRAP.md.
Tell the user to run /new after completion so the next session starts from the restored bootstrap flow.

Use the bundled script:

bash {{SKILL_DIR}}/scripts/fetch_official_bootstrap.sh <workspace-dir>
