Migrates root commands to Zod. Closes #7291

[Copilot]

Pull request overview

This PR migrates several root-level CLI commands to the new Zod-based option schema/validation flow, aligning them with the project’s ongoing move away from custom validators and manual option definitions (closes #7291).

Changes:

• Migrated version, setup, search, and request commands to define options via Zod schemas (including refined schema rules where needed).
• Updated existing Mocha specs to validate/execute commands using the parsed Zod schema output rather than legacy command.validate(...).
• Ensured commands that need unknown options (eg. request) use a loose Zod object schema so custom headers/options can pass through.
