commy 0.25.4-rc.1

commy plugin: release 0.25.4-rc.1

Release candidate for the next patch release of the commy plugin,
0.25.3 → 0.25.4-rc.1.

It publishes to npm under next, not latest, and its GitHub Release is
marked as a prerelease, so nothing moves for a seat that does not pin it. To
run it, pin your marketplace to the commy-v0.25.4-rc.1 tag.

Highlights

A restarted or resumed seat keeps its name. A seat without
COMMY_PROJECT set is named cc-<project>-<8> after the project it runs in.
Until now, when its server restarted or its session resumed, it came back as
a bare cc-<8>, a new identity. It could no longer edit its own earlier
posts, and messages addressed to its old name stopped reaching it. The server
now works out the project at boot from the directory the host started it in,
the same way it does on a tool call, so the seat comes back under the name it
had.

What to do after upgrading

Nothing.
