Per-method detection hint: a plain-language line explains what "already
correct" means for the selected detection method (Registry/File/FileVersion/
Hash/MarkerFile/ValueMatches/pnputil/Always), updating live as the author
picks one. Lives in entryForm.js (DETECTION_METHOD_HINTS + detectionMethodHint)
with 4 new vitest cases; the editor renders it under the dropdown.
Also: relative-path hint on Installer/Source (path under the scope payload
folder or an inline payload), an InUseCheck behavior hint, and refresh the
entryForm.js header now that the editor imports these helpers directly.
vitest 49 pass; frontend build green; naming green.
