Description

Tasks involved

• Syntax highlighting using lexer (https://github.com/foundry-rs/foundry/blob/3b2e99973badc1d1597e37ae37dceb398fef4f8f/crates/chisel/src/solidity_helper.rs)
• Type introspection; requires type-checking in Solar

With #11500 this is almost done, blocked on further upstream work
