fix: integrate AG-UI schema drift into auto-remediation pipeline

drift-report-collector clones canonical ag-ui repo via fs.existsSync,
runs schema drift test, merges into single report; exits 1 if skipped.
test-drift.yml notification distinguishes AG-UI vs HTTP drift; uses jq
for safe JSON. fix-drift.yml clones ag-ui, adds continue-on-error on
autofix with success() guard on PR creation, fixes Slack messaging.
fix-drift.ts: corrected agui-handler.ts references, SDK type in prompt,
flexible changelog title, ENOENT-specific catch, reordered badge checks,
exit code 4 for no-changes, version bump wrapped in try/catch.
Test coverage updated for BUILDER_TO_SKILL_SECTION and SDK type output.
