Ben McClelland 062bf0bf47 feat: add best-effort O_DIRECT support for posix put/get-object put-part ...

This change introduces an opt-in O_DIRECT mode for POSIX object data paths while
keeping behavior safe and predictable across different filesystems and kernel
constraints. We now use direct I/O when available and beneficial, but preserve
correctness by falling back to buffered I/O when runtime read behavior indicates
alignment or capability mismatches.

The implementation keeps fast paths available for full-object reads and
descriptor-to-descriptor copy operations so kernel-level optimizations can still
be used where possible. At the same time, it avoids global assumptions from
single runtime failures and performs fallback at the stream level so requests
can continue successfully without broad feature disablement.
