fix(ui): suppress initial loading flash and drop stale file-list responses

Bubble Tea delivered the first WindowSizeMsg before filesLoadedMsg, so between
ready=true and the async ChangedFiles returning, View() painted the populated
two-pane layout with an empty tree and "no file selected" — a 100-500 ms flash
on larger repos.

Gate View() on a new filesLoaded flag: show "loading..." while !ready, then
"loading files..." while ready && !filesLoaded. handleFilesLoaded flips the flag
first thing, including on error, so the loading screen always exits.

Also tag filesLoadedMsg with a seq captured at load time and drop mismatched
messages in handleFilesLoaded. toggleUntracked (and any future reload site) bumps
filesLoadSeq so an older in-flight ChangedFiles can't overwrite the tree after
the user toggles state.
