[plan] Wire idle custom agents to matching workflows (9 of 11 agent files unused)

[github-actions]

Objective

Wire up idle custom agent files from .github/agents/ to workflows that match their purpose, as identified in discussion #26727. Currently 9 of 11 agent files are unused.

Context

Per the Copilot CLI Deep Research report (discussion #26727), only technical-doc-writer (2 workflows) and ci-cleaner (1 workflow) are active. Nine purpose-built agent personas sit idle while generic Copilot handles tasks those agents were designed for.

Approach

1. Review the idle agent files to understand each agent's persona/purpose:

   • .github/agents/contribution-checker.agent.md
   • .github/agents/grumpy-reviewer.agent.md
   • .github/agents/adr-writer.agent.md
   • .github/agents/agentic-workflows.agent.md
   • .github/agents/developer.instructions.agent.md
   • Other idle agents listed in the research report

2. Match agents to workflows by purpose:

   • contribution-checker → contribution-check.md (purpose-built agent already exists for this!)
   • grumpy-reviewer → code review workflows (check .github/workflows/ for review-related workflows)
   • adr-writer → ADR creation tasks / archie.md
   • agentic-workflows → workflow generation/editing tasks

3. For each matched pair, add the agent field:

   engine:
     id: copilot
     agent: contribution-checker

4. Recompile: make recompile

5. Validate: make agent-finish

Files to Modify

• .github/workflows/contribution-check.md — add agent: contribution-checker
• Other matched workflows (identify during audit)
• Corresponding .lock.yml files regenerated by make recompile

Acceptance Criteria

• contribution-check.md uses agent: contribution-checker
• At least 3 additional workflows wired to their purpose-built agents
• Each matched agent file purpose aligns with the workflow's task
• All modified workflows compile successfully
• make agent-finish passes
