Crate byteor_transport_shm 

Shared-memory transport utilities (open/create/validate).

This crate will own OS-facing mapping logic and treat SHM as untrusted input.

Crash / cleanup semantics

Regions are file-backed mappings. If a process crashes, the backing file may remain on disk. Subsequent openers will:

• validate layout compatibility once initialization is complete
• wait for a bounded time if the mapping is observed in an “initializing” state
• fail closed with Error::Layout(indexbus_core::Error::NotInitialized) if initialization does not complete (e.g. the initializing process crashed)

Best-effort cleanup is performed by callers (tests/benches remove their temp files). Operator tooling may also remove stale mapping files as needed.
