Teknium 42a6d761d2 fix(bot-relay): add shutil.which step to CLI resolution and pin utf-8 decoding on delivery subprocess
Salvage hardening on top of #93601 (with #93597 covering the same core
mechanisms) for #93590:

- _hermes_cli(): after the venv-sibling check (hermes.exe on win32),
  try shutil.which('hermes') before the bare-name fallback, so
  environments with a PATH but no venv sibling resolve exactly what an
  interactive shell would. Platform test switched os.name -> sys.platform
  ('win32') per repo convention.
- tui_gateway/methods_bot_relay.py deliver: pin encoding='utf-8',
  errors='replace' on both subprocess.run sites — without them the
  child's UTF-8 output is decoded with the locale codec (cp1252/GBK on
  Windows), mangling non-ASCII replies or raising on undecodable bytes.
- Regression tests: shutil.which resolution step, bare-name fallback
  with which=None, and encoding-pin assertions in the deliver transport
  test.
