ci: daily code health analysis agent #13
Description
Add an agentic workflow that runs daily to analyze the codebase for cleanup opportunities.
The agent should read the entire repo, identify genuine issues (refactoring, dead code, inconsistencies, stale docs, dependency hygiene), and open issues with root cause analysis and clear specs for resolving them.
Constraints:
- Max 2 issues per run
- Skip anything already caught by CI (ruff, pyright, bandit)
- No nit-only issues — bundle small nits into meaningful cleanups
- Assign copilot to work on created issues
- If nothing worth fixing is found, create no issues
