fix(cli): align delete command wording with owner permissions

[lc0rp]

Summary

• update clawhub delete|hide|undelete|unhide command descriptions to state owner/moderator/admin access
• update delete command confirmation suffix text to match the same permission model

Rationale

Backend soft-delete already allows owners to manage their own skills, and only requires moderator/admin for non-owners (convex/skills.ts, setSkillSoftDeletedInternal). CLI wording was stale and implied owners were blocked.

Testing

• bunx vitest run packages/clawdhub/src/cli/commands/delete.test.ts
• bun run lint

Refs #413

Greptile Summary

Updated CLI command descriptions and confirmation prompts to correctly reflect that skill owners can manage their own skills' soft-delete status without requiring moderator/admin privileges. The backend logic in convex/skills.ts (setSkillSoftDeletedInternal) already implements this permission model: it allows owners to manage their own skills and only requires moderator/admin access for non-owners.

Confidence Score: 5/5

• Safe to merge - straightforward text-only documentation fix
• Changes are purely textual updates to CLI help strings that align with existing backend implementation, no logic changes, and tests pass
• No files require special attention
