Summary

• The lint CLI displayed info-level findings with the warning ⚠ icon and counted them in the warning total
• JSON output correctly reported severity: "info" but human output said "1 warning(s)"
• Now info findings show a distinct ℹ icon and the summary includes a separate info count

Reproducer

# Create composition with timed element missing class="clip"
npx hyperframes lint
# Was: "⚠  timed_element_missing_visibility_hidden ... 0 error(s), 1 warning(s)"
# Now: "ℹ  timed_element_missing_visibility_hidden ... 0 error(s), 0 warning(s), 1 info(s)"

Stack

6/8 — Depends on #126. Pairs with #126 (core linter change).

Two issues:

1. Missing pluralization for info count in check-hyperframe-static.ts

formatCounts outputs "3 info" instead of "3 infos". Warnings get proper conditional pluralization (warning vs warnings), but info doesn't:

// Current
parts.push(`${result.infoCount} info`);

// Should be
parts.push(`${result.infoCount} info${result.infoCount === 1 ? "" : "s"}`);

2. Verify findings loop in check-hyperframe-static.ts

The CLI lint command now has a three-way severity prefix (✗ / ⚠ / ℹ), but the findings output loop in check-hyperframe-static.ts is not in this diff. If it still uses a two-way check, info findings will render with the warning prefix there — the same problem this PR fixes in the CLI.

[miguel-heygen]

Addressed: added pluralization for info count (info → infos). The check-hyperframe-static.ts findings loop already uses severity.toUpperCase() which correctly outputs "INFO" — no change needed there.
