Salpa 0.2.2

An upgraded app can now see the Salpa Hub.

If you installed Salpa before the Hub became the official package source, your app
kept pointing at the old, private catalog URL after every upgrade. It failed in
the most convincing way possible: the request 404s, the Marketplace falls back to
the bundled copy and stays populated, and the source keeps reporting a fresh
"last synced" time on every launch. Nothing looked wrong — you just never saw
anything published after the day you installed.

Salpa now repairs that on startup. It also drops the stale local fallback that
kept the failure quiet in the first place.

Also in this release:

• Multi-node packages installed through /api/marketplace/install now stage their
  shared environment, instead of silently falling back to running without it.
• "Flush queue" now clears cancelled jobs too, rather than leaving them on the
  Jobs page after a flush that claimed to clear everything.

Nothing here changes how workflows run. If your app is working, this is a quiet
upgrade; if your Marketplace has looked frozen for a while, this is the fix.
