using-holodeck SKILL.md references commands that don't exist on main (list/status/ssh/scp/cleanup/os list)

[ArangoGutierrez]

Found during PR #812 review.

The shipped using-holodeck skill at pkg/skill/data/skills/using-holodeck/SKILL.md documents these workflows:

• `holodeck list` / `holodeck list -o json`
• `holodeck status `
• `holodeck ssh ` / `holodeck ssh -- nvidia-smi`
• `holodeck scp :`
• `holodeck delete ` (this one exists)
• `holodeck cleanup vpc-`
• `holodeck os list`

But on `main` today only `create`, `delete`, and `dryrun` are registered (see `cmd/cli/main.go`). AI agents installing this skill will be told to run commands that don't exist and will hallucinate.

PR #812 shipped the aspirational content per explicit Team Lead override (with a documented note that other subcommands would land in separate PRs). This issue tracks the reconciliation needed before `v0.3.0` cut:

• Option A: trim `SKILL.md` to the actual command surface on `main` (`create`, `delete`, `dryrun`) and re-grow it as commands land in separate PRs.
• Option B: implement the referenced subcommands (`list`, `status`, `ssh`, `scp`, `cleanup`, `os`) and merge them before `v0.3.0` cut.

The v0.3.0 release is in a bug-fix sprint, so Option A is the lower-risk path absent a strong reason to expand scope. Either way, this should not ship to users as-is.
