Add wasm-opt-for-rust maintenance grant

[brson]

Project Abstract

wasm-opt for Rust is a project to create Rust bindings to Binaryen's
wasm-opt tool. It allows creators of WebAssemly toolchains
written in Rust to directly optimize their WebAssembly output instead of
calling a 3rd-party non-Rust binary.

It has been integrated into

• Ink!'s cargo-contract
• Substrate's wasm-builder
• Stellar's Soroban CLI

This grant will primarily provide funding to update the wasm-opt crate
following new releases of Binaryen, after which we will also upgrade
cargo-contract and wasm-builder.

Grant level

• Level 1: Up to $10,000, 2 approvals
• Level 2: Up to $30,000, 3 approvals
• Level 3: Unlimited, 5 approvals (for >$100k: Web3 Foundation Council approval)

• I have read the application guidelines. this document doesn't exist
• A BTC, Ethereum (USDT/USDC/DAI) or Polkadot/Kusama (aUSD) address for the payment of the milestones is provided inside the application.
• The software delivered for this grant will be released under an open-source license specified in the application.

I marked this as a level 3 because the total possible yearly budget is 72k USD, but I also included text indicating that I don't expect to spend that much, possibly significantly less. How the monthly budget is calculated is included in the text.

Note that this requests funding to fix brson/wasm-opt-rs#40, in which upstream Binaryen does not handle Unicode correctly on windows. It is a significant bugfix and will take a number of hours.

Thanks a lot for the application. We recently discussed with our legal department that our current terms and conditions don’t fully cover maintenance agreements. Would it be possible to sign a regular contract for this via DocuSign? If so, I would mark the application as ready for review here to get the necessary number of approvals, but we would still need to sign a separate document before we merge it once enough people have approved it.

[brson]

@Noc2 Yes, I can sign a contract via DocuSign.

[Noc2]

Great! In this case, I will mark the application as ready for review, and I’m personally happy to go ahead with it.

Thanks @brson I agree that this will help for ink! and Substrate maintenance, happy to approve!

[takahser]

@brson I'm also happy to approve.
CC @Noc2 - Just FYI, so you can move on with the DocuSign contract.

[Noc2]

@brson Just to keep you posted: We are currently drafting the contract and will share it with you shortly. The grant is already officially accepted since it has five approvals.

[Noc2]

The agreement is signed, so I’m going to merge it. Thanks!

[brson]

Thanks all!
