maven.progmasoft.com/tazel serves the Gradle plugin of Tazel and its
plugin marker beside tazel-api, versions 0.2.0 through 0.4.0.3, but the
runbook named only the API. It now lists all three and shows how a
release stages the Gradle plugin: its build has no staging repository,
so an init script adds the same one the API uses.

Accept plugin versions of up to five numbers

Tazel takes A.B.C, then .D, .E and -METADATA if needed, so the descriptor
check follows it.

Accept plugin versions of four numbers

Progmasoft's releases move to four numbers, and the plugins publish here.

Serve the Progmasoft mark as the site icon

The sites declared no icon and /favicon.ico answered 404, so search
engines and assistants that show a site's icon (DuckDuckGo, ChatGPT)
fell back to a gray placeholder; the only copy of the mark was the BIMI
logo for mail.

The app now has the Next.js icon files, so every page links them:

- app/icon.svg: the four squares of the BIMI logo, cropped to the mark
  so it fills a browser tab, on a transparent field.
- app/favicon.ico: the same mark at 16, 32 and 48 pixels (PNG entries),
  for clients that ask for /favicon.ico without reading the page.
- app/apple-icon.png: 180 pixels on the white field of the BIMI logo,
  since iOS fills transparency with black.

The proxy rewrites paths per host, which would send /icon.svg on the
account, ViGet and the other hosts into their own page trees; the
matcher now skips the two new files as it already skipped favicon.ico,
so every Progmasoft host serves the same icons.
