ruff builtins not working with shebangs

[whatisaphone]

The builtins "ruff" and "ruff_format" should use type = "python", rather than globs, so that extensionless files with shebangs are detected.

Repro

mise.toml:

[tools]
hk = "1.54.0"
ruff = "0.15.20"

hk.pkl:

amends "package://github.com/jdx/hk/releases/download/v1.54.0/hk@1.54.0#/Config.pkl"
import "package://github.com/jdx/hk/releases/download/v1.54.0/hk@1.54.0#/Builtins.pkl"

local linters = new Mapping<String, Step> {
    ["ruff_format"] = Builtins.ruff_format
}

hooks {
    ["fix"] {
        fix = true
        steps = linters
    }
}

Steps:

git init
echo 'a=1' > x.py
echo $'#!/usr/bin/env python\n\na=1' > y
chmod +x y
hk fix

Expected result

Both x.py and y should be formatted

Actual result

Only x.py is formatted

Thanks for the detailed repro — confirmed. Both Ruff builtins were still filtering exclusively with .py/.pyi globs even though hk already detects extensionless Python scripts from their shebang.

I switched ruff and ruff_format to types = List("python") and added regression coverage for both builtins in #1147.
