v0.3.1

What's New

• CI evidence gating: Governance workflow template now runs charter adf evidence --auto-measure --ci on PRs when .ai/manifest.adf is present, automatically validating metric ceilings before merge.
• Scorecard evidence: Charter's own governance scorecard pipeline now includes ADF evidence output alongside validate and drift results.

This closes the governance loop — every PR gets LOC ceiling checks automatically.
