Fix doc issues in README and LLM_USERS.md

- Remove duplicate import in LLM_USERS.md client example
- Add missing labels to to_remote call in LLM_USERS.md

Add --ws-path for runtime URL resolution, test for lazy_guard fix

--ws-path builds the WebSocket URL at runtime from window.location,
so one compiled bundle works across all subdomains. --ws-url and
--ws-path are mutually exclusive.

Breaking change: rpc_config.ws_url is now a function (ws_url())
instead of a constant, for both modes.

Also adds regression tests for the bool.lazy_guard fix (issue #9)
that prevented the walker from hanging on recursive type graphs.

Add ETF atom pre-registration for safe binary_to_term decoding

The generator now produces an Erlang FFI file (rpc_atoms.erl) that
pre-registers all constructor atoms discovered by the type graph
walker, plus framework atoms used by the wire protocol. The generated
dispatch module calls ensure() via @external on the first RPC call,
guarded by persistent_term so it runs exactly once per VM lifetime.

This allows binary_to_term([safe]) to be used in libero_wire_ffi.erl,
closing the atom exhaustion attack surface without breaking legitimate
client payloads.
