Lucas Fernandes Nogueira 5de7ebfc95 fix(fs): do not deserialize customFlags from IPC (#3634)
In plugins/fs/src/lib.rs OpenOptions, custom_flags was deserializable
from the `open` command arguments even though it is not in the TS types,
so a webview with a read-only permission set could pass arbitrary open(2)
flags such as O_TRUNC.

The field is now #[serde(skip)]; Rust callers still set it through
OpenOptionsExt. Rejecting write/truncate/create options of `open` under
read-only sets changes permission semantics and is deferred to v3.

Security: the open command no longer accepts a customFlags option from the webview. It was not part of the JavaScript types and let the webview pass arbitrary open(2) flags (e.g. O_TRUNC) to files it may only read. OpenOptionsExt::custom_flags still works from Rust.
