Take the Tala products out of the catalog and describe the new Tazel

Tala and its tools are no longer developed (2026-11-10), and tala.run,
talac.tala.run, talafmt.tala.run and talalint.tala.run lead to a notice
that answers 503. The catalog still offered Tala, talac, talafmt and
talalint with "Visit the site" buttons into that notice, and described
Tazel as the build system of Tala.

- Tala, talac, talafmt and talalint leave the catalog in all four
  languages, as Xide did; their product pages answer 404.
- The catalog names Tazel and Catch3.
- Tazel is described as it is now: it builds C, C++, Objective-C,
  Objective-C++ and Zig from MODULE.kts and BUILD.kts, finds Clang, GCC
  and zig cc, builds for other triples, is incremental per action, and
  runs commands of tazel_custom.txt. Nothing it does not do yet (ViGet
  packages, plugins) is promised.
- The site tests list the two products and route through them.

Answers the review of website#58, which found the product links leading
