docs: remove hermes setup from install flow, point to hermes model/tools instead

The installer already handles full setup (provider config, etc.), so
telling users to run 'hermes setup' post-install is redundant and
confusing. Updated all docs to reflect the correct flow:

1. Run the installer (handles everything including provider setup)
2. Use 'hermes model', 'hermes tools', 'hermes gateway setup' to
   reconfigure individual settings later

Files updated:
- README.md: removed setup from quick install & getting started
- installation.md: updated post-install, manual step 9, troubleshooting
- quickstart.md: updated provider section & quick reference table
- cli-commands.md: updated hermes setup description
- faq.md: replaced hermes setup references with specific commands
