Summary

• The linter computed warningCount as findings.length - errorCount, which lumped info-severity findings into the warning count
• Now counts warnings and infos separately with explicit filters
• Adds a new infoCount field to HyperframeLintResult

Reproducer

# Create composition with timed element missing class="clip"
npx hyperframes lint --json | jq '{warningCount, infoCount}'
# Was: {"warningCount": 1}  (but severity was "info")
# Now: {"warningCount": 0, "infoCount": 1}
