Withhold a component's freshness while it is being built

Nothing re-reads the manifest during a run, so the "out of date" note
beside a running progress bar is the answer from before the button was
pressed -- shown for the length of a build, next to the work that is
making it wrong.

The card now reads a busy component's freshness as unknown, in the one
place the list of components is built for the cards, so the row's note
and the sibling-mismatch warning both go quiet. Same condition as the
one that disables the Update button.

+- **A card being worked on has no freshness, rather than the one from
+  before the press.** Nothing re-reads the manifest during a run -- the
+  entry was fetched before the button was pressed and read again only
+  once the run is over -- so "out of date" drawn beside the bar that is
+  making it current is last minute's answer wearing this minute's
+  clothes. `UpdaterScreen` therefore maps a busy component's `freshness`
+  to `unknown` in the one place the component list is built for the
+  cards, which is what makes both readers of it -- the row's own note and
+  `MismatchedPairNote` -- go quiet without either having to know why. The
+  condition is deliberately the same pair that disables the Update button
+  (`projectState.busy || componentState.busy`): what cannot be acted on
+  is exactly what cannot be measured just now. It comes back the instant
+  the run ends, still saying "out of date" if the build failed, because
+  by then the entry has been read again -- withheld is not the same as
+  cleared.
 - **A project's own `.dev-updater.ron` is a request, never an
   instruction.** It only runs once accepted from the phone, which copies
   it into `config.ron`; `AppEntry::pending_declaration` is the whole gate.
