feat: enable js-tracer feature

[georgehao]

• Add js-tracer feature to reth-rpc-builder in workspace Cargo.toml
• Enable js-tracer feature for reth-rpc-eth-api and reth-rpc-eth-types in node crate
• Add js-tracer feature definition in node Cargo.toml

This enables JavaScript tracer functionality for debugging transactions in the rollup node, following the pattern from scroll-tech/reth PR #334.

Why did you introduce nightly builds?

Why did you introduce nightly builds?

I think maybe we will introduce more other features that we don't want to introduce to the stable in the future. So I name this nightly. it's not the rust nightly. wdyt? or change it to unstable?

Oh I see, I had misunderstood and assumed you were using rust nightly. I think nightly is fine.
