Module FileSystem 

FileSystem atoms - two tiers:

• Managed: legacy handlers that route through FileSystemReader/FileSystemWriter traits on the Application RunTime. Currently only the binary read/write variants are wired into dispatch; the rest are preserved for future reuse.
• Native: URI-aware direct tokio::fs handlers that Wind/Sky call via file:* channels.

No pub use - every call site qualifies through Managed::<Atom> or Native::<Atom>.
