Description

Cargo project loading fails due to multiple Cargo configuration and dependency issues across different crates.

The following errors were found:

1. cross-chain-airdrop/Cargo.lock

   • Cargo fails with:

     package `thiserror` is specified twice in the lockfile
     

2. miners/rust/Cargo.toml

   • reqwest version 0.13 is configured with the unsupported feature:

     rustls-tls
     

   • reqwest 0.13 uses:

     rustls
     

3. rips/Cargo.toml

   • Cargo cannot find:

     benches/entropy_bench.rs
     

     or:

     benches/entropy_bench/main.rs
     

   • Cargo also cannot find binary:

     rustchain-miner
     

4. rust-tools

   • Workspace references:

     sdk/Cargo.toml
     

     but the file does not exist.

5. rust-tools/examples/rustchain-sdk/Cargo.toml

   • bip39 and ed25519-dalek are declared under [features] instead of [dependencies].

6. rust-tools/examples/rustchain-sdk

   • Missing crate entry file:

     src/lib.rs
     

     or:

     src/main.rs
     

7. rustchain-miner

   • reqwest 0.13 uses the outdated feature:

     rustls-tls
     

     instead of:

     rustls
     

Expected behavior

I mentioned it in "what happened"

Steps to reproduce

1. Clone the RustChain repository.
2. Open the project in RustRover.
3. Allow RustRover to load the Cargo workspace.
4. Run Cargo metadata/build:
