[r266-tech]

Closes #8488

Summary

PR #7997 added hermes backup and hermes import as new top-level CLI commands but website/docs/reference/cli-commands.md was not updated.

This PR adds:

• Both commands to the Top-level commands table
• Detailed hermes backup section with options (-o/--output) and usage examples
• Detailed hermes import section with arguments (<zipfile>, --force) and usage examples

Changes

• website/docs/reference/cli-commands.md — +47 lines (docs only, no code changes)

Thanks for the contribution! This documentation was already added to main before this PR was opened.

• hermes backup and hermes import appear in the Top-level commands table at lines 53–54 of website/docs/reference/cli-commands.md.
• Full detailed sections (## \hermes backup`and## `hermes import``) with options and examples already exist at lines 449 and 474.
• The coverage was added in commit 54e0eb24c (docs: correctness audit — fix wrong values, add missing coverage, docs: correctness audit — fix wrong values, add missing coverage #11972), which predates this PR.

Closing as the changes are already on main. — automated hermes-sweeper review
