Add macOS arm64 binary

[jansedivy]

Hello!

I noticed facebook/flow has been publishing macOS arm64 binaries since February 17th based on this commit facebook/flow@0c8fcd9.

This PR adds macOS arm64 binary to the flow-bin export.

thanks for the PR. the reason we haven't done this yet is concern over the ever-growing size of this package... already 143MB before this change!

my current thinking is that we should publish per-platform packages like [email protected] using os and cpu package.json fields, and have flow-bin depend on them all as optionalDependencies. only the one that supports your machine will get installed.

or is it fine and we should just accept the nearly 200mb packages? :)

Some ideas on how to reduce size:

1. strip debug symbols
2. build Flow with https://github.com/dinosaure/esperanto
3. use optionalDependencies for each binary like like the esbuild package

(mentioning facebook/flow#8664 to link issues together)

concern over the ever-growing size of this package

In 2025, with a bunch of developers running multi-gigabyte LLM models locally and all that, and with the Apple M chips being at fourth generation now, it seems like the perhaps we shouldn't worry about a adding another 30mb to the size?
