v0.24.0

Refresh .floppy/run: no. The shim is untouched — no commit in this
release reaches shim/run.

Minor by the 0.21.0 rule: no file layout moved and no migration is needed,
but a rite behaves differently — commit's sync no longer fails on a dirty
file it does not own, and check reads a shared clone differently.

The sync stashes over dirt it does not own (autostash)

git pull --rebase refuses on any unstaged change to a tracked file, even
with nothing to rebase — and nothing anywhere set the rebase.autoStash the
comments relied on. Measured 2026-09-13 on the owner's machine: several
projects share one clone of the workplace repository, a live session of one
project held its status file modified there, and another project's wrap died
at the sync step — commit landed, push lost, the other machine blind.
All three sync sites in commit now pass -c rebase.autoStash=true: the
workplace clone (foreign projects' dirt), the memory store (a crashed
session's half-written note), and the project repository itself (product
code a session deliberately leaves uncommitted). The stash round-trips the
dirt; nothing of it is committed or pushed.

check counts a shared clone in two piles

The workplace section counted every dirty file in the clone and said "name
them in your file list and commit closes them too" — an invitation to commit
another project's half-written work. It now counts this project's own paths
(its scope and private/common/) apart from everything else, and says of
the rest: another project's session owns them; leave them.

One project can opt out of the shared clone

The default stays one clone per repository URL. workplace_memory_dir —
which always won over the derived path — is now the documented and tested
way to give one project a clone of its own when several projects share
private_repo on one machine: isolation of the working tree without moving
any other project or machine. The recipe, including migrating an
already-wired machine, is in docs/guide/config.md under "When two projects
should not share one working tree", and tests/test-memory-dirs.sh pins
both halves of it.
