What

scripts/gen-third-party-licenses.sh embeds a Python program (python3 - <<'PY') that lists the Go modules, looks up each license, and renders THIRD-PARTY-LICENSES.md. The gate runs it on every run (third-party-licenses), so the gate and CI need python3 only for this. madtea is a Go project; this tooling belongs in Go.

Fix

A madtea-dev subcommand generates THIRD-PARTY-LICENSES.md, and with --check fails when the committed file is out of date, with the same output as today.
It keeps the VENDORED check: a tracked LICENSE, LICENCE, or COPYING file outside the repo root in a directory that VENDORED does not declare fails the check.
The gate calls the subcommand. scripts/gen-third-party-licenses.sh is removed.
The ci.yml "install system deps" step no longer installs python3, and docs/contributing/ci.md no longer lists it.

Acceptance

The subcommand's output is byte-identical to the current THIRD-PARTY-LICENSES.md.
--check fails on a stale file and on an undeclared vendored license, with tests for both.
No Python remains in the gate or in CI, and the gate is green.
