Remove Copilot agent GitHub Actions workflows

[YunchuWang]

Removes GitHub Actions workflows that install or run GitHub Copilot CLI agents in the pipeline:

• daily-code-review.yaml
• pr-verification.yaml
• self-reflection.yaml

Also removes the related Copilot agent definitions:

• daily-code-review.agent.md
• issue-triage.agent.md
• pr-verification.agent.md
• self-reflection.agent.md

I checked the remaining workflows for Copilot CLI/agent references and found none.

.github/agents/issue-triage.agent.md:1

• The PR title/description say it removes workflows that install/run Copilot CLI agents, but this change also deletes multiple agent prompt files (including issue-triage.agent.md) that aren’t mentioned. Please update the PR title/description to explicitly include removal of .github/agents/*.agent.md files (or split into a separate PR) so reviewers understand the full scope.
  .github/workflows/pr-verification.yaml:1
• With these workflows removed, any repo/org configuration that existed solely to support them (e.g., the COPILOT_GITHUB_TOKEN secret, workflow schedules, and high-privilege workflow permissions) may now be dead configuration. Consider removing the COPILOT_GITHUB_TOKEN secret (and any related documentation) to reduce credential sprawl and avoid confusion about how automation is expected to run.
