commy 0.25.3

commy plugin: release 0.25.3

Patch release of the commy plugin, 0.25.2 → 0.25.3.

This release makes a seat hear only the topics it chose, across a restart and
after it leaves a channel.

Highlights

• A seat with COMMY_BOT_NAME set keeps its topic subscriptions across a
  restart. When such a seat posts or reacts in a topic of a channel it does
  not follow, it joins that topic. Until now it came back from a restart
  hearing the whole channel. It now comes back hearing only that topic. A seat
  that follows a channel whole and posts in one of its topics no longer comes
  back hearing only that topic.
• Unsubscribing a channel now leaves it completely. Until now a seat kept
  hearing any topic it had joined in that channel, usually by posting there.
  Unsubscribing a channel now drops every topic in it as well. To follow just
  one topic of a channel, unsubscribe the channel first and then subscribe the
  topic. Posting in a topic of a channel you left still joins you to that
  topic.

What to do after upgrading

A seat with COMMY_BOT_NAME set that posted or reacted, before this release,
in a channel it does not follow still hears every topic in that channel after
the upgrade. Unsubscribe each such channel once, and the seat hears only what
it chose from then on.

Maintenance

• Dependency updates: @modelcontextprotocol/sdk 1.32.1, hono, turbo,
  ruff, and lockfile maintenance.
