Andrey VasnetsovandClaude Opus 5 908cd2f10a [UIO] Pin the append filesystem to its handle (#10092) ...

`UniversalRead::Fs` was reachable from an append handle and known to be
a `UniversalWriteFileOps`, but not pinned: `fs.open_append(..)` on it
returned some `Fs::AppendFile`, not the handle type in hand. Pin it the
way the read side is pinned, so `S::Fs` both opens `S` for reading and
hands `S` out as its append handle:

    UniversalRead<Fs: UniversalWriteFileOps<AppendFile = Self>>

Every append handle's canonical filesystem already produced itself
(`MmapFs → MmapFile`, `IoUringFs → IoUringFile`, `BlobFs<A> →
BlobFile<A>`), so this only writes down what held — the workspace
compiles unchanged.

Generic-over-`<S: UniversalAppend>` code now reaches its file-creating,
append-opening filesystem as `S::Fs` with no second associated type, and
`&impl UniversalWriteFileOps<AppendFile = S>` accepts any other producer
— the mirror of `&impl UniversalReadFs<File = S>`.
