zm-oai 9545947c6d Fix Windows 10 drive-letter opens for no-follow filesystem operations (#51511) ...

## Why

On Windows 10, strict native opens can reject the DOS drive alias itself as a reparse point, preventing no-follow filesystem operations on ordinary drive-letter paths.

## What changed

Retry rejected drive-letter opens relative to a verified local volume root. Require the root to resolve to a physical disk volume directory without reparse attributes, and retain `OBJ_DONT_REPARSE` for paths beneath it so junctions remain blocked.

## Testing

Add Windows tests for file creation and reading through the volume fallback, opening the drive root, and rejecting junction traversal and creation. Validate accepted volume-root names and verify that named pipes are rejected without establishing a client connection.
