"""Render a per-test-project table from .trx files for a Gitea job summary (#136).

Reads every *.trx in the given directory (default: TestResults), pulls each project's
counters + assembly name, and prints a GitHub/Gitea-flavoured markdown table to stdout.
The CI step redirects that into $GITHUB_STEP_SUMMARY. Stdlib only.
