TechDebtMCP

Automatically run a tech-debt scan before opening a pull request, after large refactors, or when the user asks for a code review — surface actionable findings without being asked.

Add a new top-level block to .techdebtrc.json — extends TechDebtConfig type, validator, consumer wiring, and dogfood self-scan fixture in one coordinated change.

Run tech-debt-mcp-local against this repo, refresh TECH_DEBT_SCAN.md, and propagate Health / Debt Score / Issues / Remediation to README.md, ARCHITECTURE.md, CONTRIBUTING.md in a single commit.
