Two issues from a follow-up audit on the Git Repository screen.
- Move the initial cache scan into flow `onStart` so the
newEventBundles collector is attached before scanning. Closes a small
race window where status events emitted between scan completion and
collect attachment would have been dropped.
- Distinguish "index warming up" from "no status exists" by typing the
StateFlow as `Map?` (null until first scan completes). The pill now
hides itself entirely while warming, instead of briefly rendering
the `defaultIfMissing` fallback and then flipping to the real status.
Also drops the dead public `rememberLatestStatus` helper and the
unnecessary derivedStateOf scaffolding — at the scale this screen
operates (tens of pills), the straightforward map read is fine.
