Subject: [PATCH] Move Rust examples into their crates so cargo publish picks
 them up

The previous `[[example]] path = "../../examples/rust/..."` entries
pointed at files outside the crate root. cargo only packages files
inside the crate directory, so the examples would have been silently
dropped on publish. Moving them to crates/wickra/examples/ and
crates/wickra-data/examples/ keeps them as part of the published
package and lets cargo discover them automatically (no [[example]]
override needed). README and project-layout section updated.

 The wickra-core crate is `unsafe`-forbidden, so every binding inherits a
 memory-safe implementation.
