Description
Add fuzz testing for the host function handlers so a malicious or buggy guest cannot crash or hang the host with bad input. The target is the typed FlatBuffer fs_* and net_* host functions: feed truncated or malformed FlatBuffers, out-of-range file descriptors and lengths, and adversarial paths and socket addresses, and confirm the host returns real -errno without panicking, leaking resources, or escaping the sandbox.

Research direction
Start by locating the typed FlatBuffer fs_* and net_* host function handlers and their existing tests or fuzzing entry points. Add fuzz coverage for truncated and malformed inputs, invalid descriptors and lengths, and adversarial paths and socket addresses; done means the host returns real -errno without panics, resource leaks, or sandbox escape.
