<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Medium Risk**
> Moderate risk because it changes how QA metrics are keyed/collected
and updates CI artifact production/retention; mismatches in artifact
names or parsing could silently drop metrics or skew dashboards.
> 
> **Overview**
> Updates the QA stats pipeline to generate **richer, explicitly named
metrics** (e.g., `*_tests_run`, `total_tests_defined`,
`total_tests_skipped`) and adds static source scanning to estimate
defined/skipped tests across unit, component-view, E2E smoke, and
performance suites.
> 
> The collector no longer depends on a passed `WORKFLOW_RUN_ID`; it now
resolves the **latest successful `ci.yml` run on `main`** via the GitHub
API and pulls additional artifacts to include **coverage percentages**
for unit and component-view tests.
> 
> CI workflows are adjusted to support this by producing/uploading new
coverage-summary artifacts and setting **7-day retention** on several
uploaded artifacts, and the `qa-stats.yml` workflow switches from
`workflow_run` triggering to a **daily scheduled run**.
