ci: declare contents: read workflow permissions

[zen-agents]

Why

CodeQL actions/missing-workflow-permissions flags this workflow because it had no explicit permissions: block, so the default GITHUB_TOKEN was overly broad.

Change

Add a top-level least-privilege block:

permissions:
  contents: read

This matches the estate pattern already on agency-automations / creditscan-v2 / ZenSms.

Scope

• Path: .github/workflows/ci.yml only
• No pin, job, or step changes
• Do not merge from this PR unless a later steward pass is assigned

Summary by CodeRabbit

• Chores
  • Updated automated workflow permissions to use read-only access for repository contents.

Approved. Cursor Bugbot was not present after the first check poll, so that signal was skipped; the remaining evidence is a least-privilege contents: read addition to .github/workflows/ci.yml with no findings requiring human review. No reviewers were assigned.
