Fix Rust cargo metadata issues

[qiann0512-gif]

Summary

• update reqwest 0.13 TLS features to use the supported rustls feature
• remove stale RIP binary and benchmark targets that point to missing files
• fix Rust tooling example paths and optional dependency declarations
• remove duplicate thiserror entries from the cross-chain airdrop lockfile

Why

Several Rust manifests currently reference unsupported features, missing targets, or incorrectly categorized optional dependencies. Those issues prevent Cargo from reading or building the affected packages cleanly.

Fixes #8095.

Validation

• Confirmed all declared local manifest targets now exist with a static path check.
• Confirmed duplicate thiserror/thiserror-impl lockfile entries were removed.
• git diff --check passes.
• Could not run cargo metadata locally because cargo is not installed in this environment.
