sandbox: do not assume home is inside `/Users`

build(deps): bump rubocop-rspec from 1.40.0 to 1.41.0 in /Library/Homebrew

Add completion configuration for non-Homebrew fish

It’s not uncommon to use `/var/${USER}` as a home directory, especially
for shared or CLI-only users.

This fixes an issue where a formula that requires `xcodebuild` is
`brew install`ed from such a shared or CLI-only user account.
In that case, `xcodebuild` would fail because it is denied writing to
`/var/${USER}/Library/Developer/Xcode`.

sorbet/files.yaml: add new files

dev-cmd/audit: tweak checksum audit.

Compare against the latest `origin/master` checksum rather than
whatever the previous one was.

Use `atomic_write` instead of deleting and writing file.

sorbet/files.yaml: set utils files to true

Set utils/bottles.rb, utils/shell.rb and utils/svn.rb to true so that
type errors in these files may be reported by Sorbet

(cherry picked from commit fd3db131b0da78169fdff2031180a2bebe3cbb84)

dev-cmd/update-license-data: don't use partial downloading & fix --fail-if-changed

dev-cmd/bottle: fix positioning of bottle block in some cases

Check installed dependents on install and reinstall

Add CodeCov YAML file.

It's not sufficient to do this merely on `brew upgrade` because
`brew install` and `brew reinstall` can also result in formulae being
upgraded.

This requires moving logic from `cmd/upgrade.rb` to `upgrade.rb`. To
save you searching the diff the changes that resulted from doing that:

- Query the installed formulae from class state in `FormulaInstaller`
  rather than the (incomplete) list that we passed into it.
- Don't output the "Checking dependents" message. It was there for
  systems and configurations where this is slow but for most users
  and most installations this will be a (annoying, noisy) no-op.
