Pull request overview

This PR bumps the workspace version to 22.0.10 for a release branch, and also includes a few SDK behavior fixes with accompanying tests/snapshots.

Changes:

• Bump workspace/crate versions from 22.0.8 → 22.0.10 (and update Cargo.lock accordingly).
• Prevent integer overflow wrapping in Bytes::slice, Vec::slice, and prng().gen_range by switching to checked arithmetic.
• Fix #[contractimpl] impl Trait for Type export generation to call the trait method via UFCS, and add regression tests + a new snapshot.

The PR title/description indicate this is only a version bump/release branch, but this diff also includes functional changes (overflow handling changes in slice/gen_range, plus a #[contractimpl] behavior fix and new tests). Please update the PR title/description (or split into separate PRs) so the release branch accurately communicates the included behavioral changes.
