Misc #21369: Propose Max Bernstein (@tekknolagi) as a core committer

Proposal

I'd like to propose Max Bernstein (@tekknolagi (Maxwell Bernstein)) as a committer. He has a strong background in compilers, having previously worked on CPython/Cinder at Meta, and has demonstrated leadership in designing and optimizing ZJIT.

Given that he is leading the development of the ZJIT IR and has been making a lot of contributions, I believe he should be empowered to merge such changes himself.

I'll include his message below for reference:

Max Bernstein's Message

I have been working on Ruby since December 2024. My main contributions so far have been to ZJIT:

• The high-level IR (HIR) data structures
  • The IR
  • The type lattice https://github.com/Shopify/zjit/pull/19
• Transforming YARV bytecode into HIR
• Optimization on HIR, such as
  • Type inference https://github.com/Shopify/zjit/pull/23
  • Constant folding https://github.com/Shopify/zjit/pull/74
  • Direct calls https://github.com/Shopify/zjit/pull/84
  • Strength reduction
  • Dead code elimination (DCE) https://github.com/Shopify/zjit/pull/89

After we moved the ZJIT repo into ruby/ruby, I have continued contributing (see all PRs). I would like to continue contributing to ZJIT and eventually to other parts of Ruby too. Being a maintainer would make it easier to work on ZJIT, especially as we continue the project bringup phase.

I'm working closely with Max and I can recommend him to join the team.

+1 Max is doing great work on ZJIT

+1. I'm quite surprised Max isn't already a committer, given his almost daily contributions.
