docs: improve CLI reference SEO metadata

[mintlify]

Summary

Improve title and description frontmatter on the CLI reference page for SEO.

Changes

• Expand title from generic "CLI" to "hud CLI command reference" (descriptive, ~25 chars)
• Lengthen description from 60 to ~155 chars, listing key commands users actually search for (init, build, push, run, eval, debug)

---

Note

Low Risk
Documentation metadata only; no runtime, API, or CLI behavior changes.

Overview
Updates only the Mintlify frontmatter on docs/v6/reference/cli.mdx for search and social previews.

The title changes from the generic "CLI" to hud CLI command reference. The description is expanded to a longer, keyword-rich blurb that names common CLI verbs (init, build, push, run, eval, debug) and mentions presets and flags. Page body and commands are unchanged.
