Removes the last use of the `brew cask` subcommand, which no longer
works.

Also replaces `launchdns` with `dnsmasq`, which has been disabled in
`homebrew-core` due to the upstream project being archived.

`musl.cc` is no longer available via GitHub Actions, so switching to a
GH-hosted alternative to unblock cross-compilation

Update asdf integration for 0.16

Allow skipping libevent when compiled with Crystal 1.15.0+

Crystal 1.15.0+ includes the lifetime event driver that natively integrates
with the OS on supported platforms, making compiling and linking to libevent
unnecessary

The version of term-prompt locked depending upon an older version of term-reader
that relied undocumented API that was specific to Crystal's libevent implementation
so this also upgrades the affected packages to remove the hard dependency on libevent

Update pkg-config to pkgconf in Homebrew

Homebrew moved to pkgconf, and now pkg-config is just an alias

Release 0.7.0

strap.sh removal of git setup complicates some assumptions
built into mstrap that will need to be rethought. In the
meantime, pinning is fine for the time being (it's unlikely to
receive further updates)

This reverts commit 4ed67f377443266ff7e0fb53680bb8fd5bebbd2e.

Set git user details via mstrap

It's not a secret, but its not really usable by anyone else

strap.sh no longer configures git, so we'll do it ourselves

ci: install Ruby stdlib on archlinux smoke tests

This is for some reason optional now, so needs to be installed
seperately

Rename --debug to --verbose

Remove version property from services-internal.yml

Documentation/DocumentationAdmonition: these don't need to be reported by Ameba
Naming/BlockParameterName: I'm okay with single letter block params in some cases

Detect xcode git shim and handle appropriately

xcrun is also a shim, and because we're optimizing for strap.sh & Homebrew, they'll install Xcode CLT anyway. Therefore, there's little value here in trying to be extra robust by using xcrun

Git lookup occurs before lsb_release might be available for distro
determination, leading to a quick crash from an UnsupportedDistroError.

Until we have a better way of doing distro detection, we'll need to avoid
doing anything distro-specific until we know lsb_release is available

Static libs are missing for OpenSSL@3 in current GitHub Actions macOS-14 runner
image is broken until it pulls in https://github.com/Homebrew/homebrew-core/pull/169721

Removed "install from API" config too, since auto upgrades are disabled anyway.
