v1.0.0 — The positions tool is removed

• The positions tool is removed. librarian-positions and the code behind it (the recall query, the
  fold and its index tables) are gone. A client that still calls it gets the standard "tool not found" error.
  Session lines already carry who decided what and why, and are what librarian-search and librarian-recent
  return. Positions already recorded stay in _librarian/positions/ as your own history: rutter no longer reads
  them, never changes them, and drops the old position tables from its index the next time it reindexes. Old
  librarian-positions lines in stateful-use.jsonl stay and are ignored. If an old rules file still produces a
  position line, the capture hook still prints its note and stores nothing; that note has no end date. A client
  that cached the old instructions keeps mentioning the tool until you restart it, or re-run the installer for
  clients that keep a copy. The installer prints a one-line reminder.

Install or upgrade: npm install -g rutter-memory.
