file_read

Streaming/handle-based file I/O across the wasm host membrane. Handles are opaque u64 values returned by file_open(); 0 means open failed (including path policy denial or bounded lock timeout). Locks are automatic and lifetime-scoped: read opens take a shared lock, write/append/read-write opens take an exclusive lock, and file_close() releases it. Lock wait is bounded by UCE_FILE_LOCK_TIMEOUT_MS (default 2000ms).
