Write a man page for velos (velos.1)

[Dave93]

Summary

There's already a docs/velos.1 stub in the repo. We should flesh it out into a proper man page so man velos works after installation.

What to do

1. Fill in docs/velos.1 with all subcommands, flags, and examples
2. Update the install script / Makefile to install the man page to /usr/local/share/man/man1/
3. Add a note in CONTRIBUTING.md about updating the man page when adding new commands

Reference

• Current stub: docs/velos.1
• Man page format: https://www.man7.org/linux/man-pages/man7/man.7.html
• You can preview with: man ./docs/velos.1

Acceptance criteria

• All current subcommands documented (start, stop, restart, list, logs, monit, mcp-server, etc.)
• SYNOPSIS, DESCRIPTION, COMMANDS, OPTIONS, EXAMPLES sections filled in
• Man page installs correctly via Makefile
• man velos works after make install

No coding required — just technical writing in man page format!
