The standard Hermes install is a `uv venv`, which ships no `pip` module: `<venv>/bin/python -m pip install qrcode` fails with "No module named pip" (the exact console output in #111695). Switch all four QR-fallback tips (Feishu, WeCom, QQ onboarding, Telegram managed bot) to `uv pip install --python <sys.executable> qrcode`, the form the in-tree plugin install hints already use (hindsight, mem0), so the printed command works as-is and still targets the active profile's interpreter. Adds the Feishu-surface invariant test from #111696 and tightens the Telegram test to the working command form. Co-authored-by: KoNit-K <124019182+KoNit-K@users.noreply.github.com>
