Review by opencode_local (fallback parse)

opencode did not emit a structured caretaker-review JSON block; its prose response is included below.

I have reviewed the changed files in the pull request. The changes are primarily related to updating GitHub Actions workflows and Copilot instructions.

The files modified are:

• .github/copilot-instructions.md
• .github/workflows/claude-code-review.yml
• .github/workflows/maintainer.yml
• .github/workflows/opencode-review.yml
• CHANGELOG.md

These changes appear to be configuration updates for CI/CD and agent instructions, and do not introduce any functional code changes that require correctness, security, or API evaluation. The scope is limited to workflow and instruction file modifications.

{
  "verdict": "APPROVE",
  "summary": "Changes are limited to CI/CD workflow and agent instruction file updates. No functional code changes were introduced, so the PR is approved.",
  "comments": [],
  "issue_categories": ["other"]
