Stefan Haller be897ce55e Bounce FILES model updates onto the UI thread
refreshStateFiles now does its git work on the worker and enqueues a
single OnUIThread closure that writes Model.Submodules, Model.Files, and
the FileTreeViewModel state together, instead of writing them directly
from the worker goroutine. refreshStateSubmoduleConfigs becomes a pure
getter (returns the configs; no model write) so the result can be
threaded into that same bounce.

The STAGING handler wraps RefreshStagingPanel in OnUIThread after
fileWg.Wait() so it sees the post-bounce file model rather than the stale
pre-refresh one — without this it would race the files bounce queued just
above it.

Bouncing the write opens a hazard the old synchronous write didn't have:
if the user switches repos while this refresh is in flight, the queued
closure would fire after resetState has replaced the model with a fresh
one for the new repo, silently overwriting it with the previous repo's
files. Guard against this with a repo generation: resetState bumps a
counter on every switch, refreshStateFiles captures it before its git
work, and onUIThreadUnlessRepoChanged drops the bounce if the generation
has moved on. This one helper is the general mechanism the remaining
scopes' bounces will use too; the same guard covers the rebase-continue
prompt, which reads Model.Files right after.

A generation counter, not a comparison of the *Model pointer: switching
away from and back to a repo reuses that repo's cached state (the same
Model pointer), which a pointer comparison would wrongly accept even
though the in-flight data is stale.

PromptToContinueRebase's Then callback (previous commit) now gets an
explanatory comment, since this is the commit that makes it necessary.

The explicit locking around these writes (RefreshingFilesMutex in
refreshFilesAndSubmodules, FileTreeViewModel.RWMutex around the write in
refreshStateFiles) is left in place for now even though it's becoming
redundant, to keep this commit focused on the bounce itself; it's removed
next.
