- plugins_cmd.py: import rewriter changed `import hermes_cli` to
`import hermes_agent.cli` but left variable usage as `hermes_cli.__file__`,
causing a NameError at runtime
- scripts/hermes-gateway: stale `from gateway.run import` (no .py extension
so it was missed by **/*.py globs)
- scripts/install.ps1: stale `tools\skills_sync.py` path, use
hermes-skills-sync console_script instead
