Chris LuandClaude Opus 5.5 53377bcb5d mount: keep a handle dirty when a write lands during its flush (#12652 )

A flush uploads the dirty pages without the handle lock, then commits the
entry under it. A write in between grows the entry's size, but its pages
are not in the committed chunks. Clearing dirtyMetadata then made the next
flush skip the commit, leaving a file with the new size and no chunk for
the write, which reads back as zeros.

Count page writes on the handle and clear dirtyMetadata only when none
landed since the flush started uploading.
