codev update --agent: Non-interactive update mode for AI agents

[waleedkadous]

Summary

Add a --agent flag to codev update that produces agent-friendly output instead of the interactive alignment flow.

Current Behavior

codev update runs an interactive process that updates skeleton files, triggers alignment, and requires human interaction.

Desired Behavior

codev update --agent should:

• Update skeleton/protocol files from the latest installed version
• Instead of interactive alignment, output instructions (or be represented as a skill) that tell the agent:
  1. What files were updated/added/removed
  2. How to merge any conflicts
  3. Commit and push the changes
• Designed to be invoked by an AI agent (e.g., as part of a cron task or maintenance workflow)

Use Case

After a new Codev release, projects need to pull in updated protocols, templates, and agents. An AI agent should be able to do this autonomously without human interaction.
