deps(v4)(deps): bump fs4 from 0.12.0 to 1.1.0 in /v4

[dependabot]

Bumps fs4 from 0.12.0 to 1.1.0.

Release notes

Sourced from fs4's releases.

v1.1.0

Changes

• Consolidate FileExt and AsyncFileExt into single crate-root traits (fs4::FileExt, fs4::AsyncFileExt) instead of generating a distinct trait per backend module. The per-backend modules (fs4::tokio, fs4::async_std, fs4::smol, fs4::fs_err2, fs4::fs_err3, fs4::fs_err2_tokio, fs4::fs_err3_tokio) now re-export the unified crate-root trait. Method-call sites that import the trait via use continue to compile unchanged; code that named two backend traits as distinct types will see them unify.
• Add blanket impls impl<F: FileExt + ?Sized> FileExt for &F and impl<F: AsyncFileExt + ?Sized> AsyncFileExt for &F, so the extension methods are now callable through shared references.
• Seal FileExt and AsyncFileExt via a private sealed::Sealed supertrait, so the set of implementing types is closed to the concrete file types fs4 already supports (and references to them). This locks in the freedom to add methods to either trait in future minor releases without breaking downstream impls.
• Add DynAsyncFileExt, an object-safe mirror of AsyncFileExt whose async methods return BoxFuture<'_, T> (alias for Pin<Box<dyn Future<Output = T> + Send + '_>>). Use it whenever type erasure is needed (Box<dyn DynAsyncFileExt>, &dyn DynAsyncFileExt); prefer the static AsyncFileExt for generic code since it has no allocation or dynamic-dispatch overhead. Every type implementing AsyncFileExt also implements DynAsyncFileExt, and the trait is sealed.
• Mark the delegating methods #[inline(always)] (skipped under tarpaulin coverage builds).

v1.0.0

1.0.0

Breakage

• Renamed FileExt::lock_exclusive / AsyncFileExt::lock_exclusive to lock, matching the stabilized [std::fs::File::lock] API.
• Renamed FileExt::try_lock_exclusive / AsyncFileExt::try_lock_exclusive to try_lock, matching [std::fs::File::try_lock].
• Changed the return type of try_lock and try_lock_shared from std::io::Result<bool> to Result<(), TryLockError>. Ok(()) still indicates the lock was acquired; Err(TryLockError::WouldBlock) now indicates the lock is held by another handle. This matches the stable [std::fs::File::try_lock] signature (Ok(false) was the nightly shape prior to 1.89).
• Removed the top-level lock_contended_error() helper. Use TryLockError::WouldBlock instead.
• Flattened the fs_std module: the FileExt trait for std::fs::File now lives at the crate root. Update imports from

1.0.1

Fixes

• Unix allocate: short-circuit on allocated blocks (metadata().blocks() * 512 >= len) instead of logical EOF. The previous metadata().len() >= len check silently turned allocate into a no-op on sparse files (logical length large, zero blocks reserved), violating the documented preallocation guarantee. The new check still skips the macOS F_PREALLOCATE re-allocate-ENOSPC path from #15, since it asks the right question: "are the blocks already reserved?" Applies to both the sync and async implementations.
• Windows statvfs: route the three GetDiskFreeSpaceExW outputs correctly. free_space now comes from lpTotalNumberOfFreeBytes (volume-wide, quota-independent), available_space from lpFreeBytesAvailable (caller-scoped, honours per-user quotas), and total_space is computed from cluster math (sectors_per_cluster * bytes_per_sector * total_number_of_clusters)

Looks like fs4 is up-to-date now, so this is no longer needed.
