Changes:

• Introduces a daily scheduled workflow that installs/builds/tests, gathers deduplication context via gh, and runs the Copilot CLI agent.
• Adds a repo-specific .github/copilot-instructions.md document to provide architectural context and invariants to AI assistants.
• Adds a .github/agents/daily-code-review.agent.md agent definition describing how the autonomous reviewer should operate and open PRs.
