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

[maxfriedmann]

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/:

Shard	Tests	Passed	Failed	Skipped
1	53	24	3	26
2	49	34	0	15
3	49	36	3	10
Expected merged	151	94	6	51

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.
