Follow-up to #87.
Problem #
Since #87, a blank New automation form shows a role="status" "Watching all repos" alert under the Lexicon field's two hint paragraphs. docs/design.md's Notices rule says alerts are "Not for standing help text: that is a hint", and not to stack an alert under two hint paragraphs that say the same thing. The alert is there before the user has typed anything, so it is standing help text, and screen readers announce it on load.
Evidence #
app/islands/AutomationForm.tsx:3354: the "Watching all repos" alert.docs/design.md: the Notices rule.
Expected #
What the alert says moves into the field's hint, or replaces one of the hints, so the field has one explanation in hint style. An alert only appears for something the user needs to act on.
Acceptance criteria #
Out of scope #
The layout jump under the Lexicon field, tracked in the "Lexicon hint jumping" issue filed alongside this one; the two are likely fixed together.
