* Renders the per-package vitest `json-summary` reports as one Markdown table.

|
*
|

|
|
* Appends to $GITHUB_STEP_SUMMARY when running under Actions so the numbers are
|

|
|
* visible on the run page without opening the log, and prints to stdout
|
||
|
|
* otherwise. Never fails the build: the hard gate is vitest's own
|

|
|
* `coverage.thresholds`, this is only a report.
