houseme c79366d42c refactor(ecstore): tidy io_uring read backend (docs + fd-cache handle) (#4732)
Two behavior-preserving cleanups to the io_uring local read backend that
accumulated as later work layered onto it:

- Reunite the `UringBackend` struct doc comment. The backlog#1145 fd-cache
  constants were inserted into the middle of the struct's doc block, so its
  opening sentences were orphaned onto `ENV_RUSTFS_IO_URING_FD_CACHE` and the
  struct itself was documented by a sentence fragment starting mid-clause with
  "through rustfs-uring's...". Move the opening back onto the struct and give
  the constant its own one-line doc.

- Fold the fd-cache handle and its lookup key into a single
  `Option<(&FdCache, FdKey)>` in `pread_uring`, so the get and the
  insert_if_fresh sites stop re-deriving `self.fd_cache.as_ref()` and
  re-matching presence. Semantics are identical, including the backlog#1176
  generation guard (`gen_at_open` snapshot before open, insert only when the
  generation is unchanged).

No functional change. The borrow/move pattern was validated against a
host-compilable reduction (the cfg(linux) path cannot be built from macOS);
CI compiles the Linux backend.
