Add a system-installed Deno language implementation. Hooks prepend deno to the configured entry, health checks run deno --version, and no environment is created. Add runner and health-check coverage.

Tests:

  • py -m pytest tests/languages/deno_test.py tests/clientlib_test.py (66 passed)

Fixes #3410

Sorry, something went wrong.

this provides nothing over language: unsupported. -- you can already prefix a command with deno in the entry

Fair point. With the current no-install/no-env implementation, language: unsupported plus entry: deno ... covers the same case. I am closing this rather than add a thin alias.
