Summary table in PR comment uses single report instead of merged data when multiple CTRF files match report-path glob

When using report-path with a glob pattern that matches multiple CTRF report files (e.g. from sharded Playwright runs), the action correctly merges data for:

• The uploaded artifact (correct totals)
• Annotations (all failures annotated)
• Insights section (aggregated historical data)

However, the Summary table in the PR comment only reflects one of the matched files instead of the merged totals.

Reproduction

3 Playwright shards each produce a ctrf-report.json, uploaded as separate artifacts and downloaded into e2e-artifacts/:

Config:

report-path: "e2e-artifacts/**/ctrf-report.json"

Logs confirm all 3 reports are read (Read 3 CTRF reports), and 6 failures are annotated via ##[error]. But the Summary table shows shard 2's numbers only (49 tests, 0 failed).

Expected behavior

The Summary table should reflect the merged totals across all matched CTRF files (151 tests, 6 failed).

Workaround

Pre-merge the CTRF reports into a single file before passing to the action, so report-path only matches one file.

Start by tracing how the report-path glob results are read and how the PR comment Summary table obtains its data. Reproduce the issue with three CTRF files matching the glob, then verify that the table reports merged totals of 151 tests and 6 failures rather than one shard's values.
