Enable writeback_cache and async_dio FUSE options (#7980)

* Enable writeback_cache and async_dio FUSE options Fixes #7978 - Update mount_std.go to use EnableWriteback and EnableAsyncDio from go-fuse - Add go.mod replace directive to use local go-fuse with capability support - Remove temporary workaround that disabled these options This enables proper FUSE kernel capability negotiation for writeback cache and async direct I/O, improving performance for small writes and concurrent direct I/O operations. * Address PR review comments - Remove redundant nil checks for writebackCache and asyncDio flags - Update go.mod replace directive to use seaweedfs/go-fuse fork instead of local path * Add TODO comment for go.mod replace directive The replace directive must use a local path until seaweedfs/go-fuse#1 is merged. After merge, this should be updated to use the proper version. * Use seaweedfs/go-fuse v2.9.0 instead of local repository Replace local path with seaweedfs/go-fuse v2.9.0 fork which includes the writeback_cache and async_dio capability support. * Use github.com/seaweedfs/go-fuse/v2 directly without replace directive - Updated all imports to use github.com/seaweedfs/go-fuse/v2 - Removed replace directive from go.mod - Using seaweedfs/go-fuse v2.0.0-20260106181308-87f90219ce09 which includes: * writeback_cache and async_dio support * Corrected module path * Update to seaweedfs/go-fuse v2.9.1 Use v2.9.1 tag which includes the corrected module path (github.com/seaweedfs/go-fuse/v2) along with writeback_cache and async_dio support.
