chore: migrate to oxfmt

[tido64]

Description

oxfmt now supports all the file types we care about: https://oxc.rs/blog/2026-02-24-oxfmt-beta

Test plan

Before:

 NX   Successfully ran target format for 61 projects (23s)


________________________________________________________
Executed in   25.16 secs    fish           external
   usr time  141.66 secs    0.33 millis  141.66 secs
   sys time   30.15 secs    3.33 millis   30.15 secs

On CI:

After:

 NX   Successfully ran target format for 61 projects (18s)


________________________________________________________
Executed in   19.50 secs    fish           external
   usr time  102.81 secs    0.36 millis  102.81 secs
   sys time   28.52 secs    1.59 millis   28.52 secs

However, if we invoke oxfmt directly at the root level, we can go even faster:

________________________________________________________
Executed in    1.41 secs    fish           external
   usr time    4.75 secs    4.85 millis    4.74 secs
   sys time    0.87 secs  106.53 millis    0.76 secs

Nice! It's great that package.json files are included. One build script nicety would be automatically running oxfmt on the files after running lint --fix as that always causes issues.
