Additional Logs / Traceback (optional)

I also checked hermes-agent==0.15.2 wheel: it still contains the old naked uv pip install --upgrade hermes-agent path, so this is not fixed there.

Root Cause Analysis (optional)

[uv, "pip", "install", "--upgrade", "hermes-agent"] Since the process is not necessarily launched with VIRTUAL_ENV set, uv refuses to infer a target environment.

Proposed Fix (optional)

[ uv, "pip", "install", "--python", sys.executable, "--upgrade", "hermes-agent", ]
