docs(test-insights): state that Detection reports on default-branch runs

[JulianMaurin]

Detection, mergify tests show, and the test search API surface only runs
from the repository's default branch; pull request runs are stored but feed
Prevention instead. A repository whose CI has only ever run on pull requests
therefore sees an empty Detection page with working uploads.

🟡 Not ready to approve

Two small wording/style adjustments are needed in the newly added Detection section to match docs writing rules and remove ambiguity.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

Documents the scope of Test Insights Detection, clarifying that it reports only on default-branch CI runs (while pull request runs feed Prevention), and cross-links this behavior from the Test Insights overview page.

Changes:

• Add a new “Which runs Detection reports on” section to explain default-branch-only reporting and what to expect if CI has only run on pull requests.
• Clarify that the same scope applies to mergify tests show and the Test Insights test search API.
• Add a “Default branch scope” key concept with a deep link to the new Detection section.

File summaries

File	Description
src/content/docs/test-insights/detection.mdx	Adds an explicit section describing Detection’s default-branch scope and related CLI/API scope.
src/content/docs/test-insights.mdx	Adds a key concept bullet that points readers to the new Detection scope explanation.

Review details

src/content/docs/test-insights/detection.mdx:23

• “Merge to the default branch” is a bit ambiguous (merge what?). Making it explicit helps readers understand they need a default-branch CI run (typically by merging a pull request).

A repository whose CI has only ever run on pull requests shows an empty
Detection page, even though uploads are working. Merge to the default branch
and the tests appear after that run completes.
