lib/test_bot: no environment hints.

These are just a bit annoying in `brew test-bot` output.

test_formulae: avoid repeated downloads of the same artifact

We can correctly follow the trail left by the PR `event.json`s but still
end up in an infinite l...

tests: improve no-API switching for named args

tests/formulae: skip online checks for OpenSSL migration PRs

These tests are a bit flaky, and I think we'd rather deal with any
failures from these checks af...

bottles_fetch: run `cleanup_during!` more often

It looks like the runner is running out of space doing this at
Homebrew/homebrew-core#133740.

test_formulae: improve bottle install logging

This revision will typically be a merge commit that doesn't appear in
the PR branch, so it would...

formulae: avoid fetching just-built dependencies

Trying to fetch a just-built dependency will result in a `brew fetch`
failure because its bottle...

Reduce bottle install logging

Some of this logging is a bit redundant, so let's skip it.

test_formulae: improve logging of cached bottle installs

Let's report the Git revisions used to make it easier to audit the state
of the repo at the time...

test_formulae: replace `node` query with `repository` query

This allows us to avoid calling the REST API to request for the commit's
`node_id`.

Reduce attempts to download artifact cache

Without credentials our attempt to download previous artifacts quickly
hits the API rate limit.

test_formulae: avoid caching PRs that have the `workflows` label

Workflow modifications can be used to compromise our cache, and we don't
want that.

tests/formulae: verify local bottles before attempting to install one

This should help minimise the probability that these bottles were
tampered with.

test_formulae: improve result caching

This will help reduce the number of times tests error out because of the
unauthenticated rate li...

We also track bottle JSON files now, so we need to remove the ones we
just built to avoid errori...

We call `verify_local_bottles` inside an `ensure` block, so calling
`exit 1` prevents any meanin...

We will use these to check whether bottles have changed, so we should
verify their integrity.

This will be more reliable that relying on the `before` property, since
formulae are built again...

Implement bottle checksum verification

This will prevent the error [^1] about unexpected bottles:

Error: Unexpected bottle: /githu...

This helps make sure there are no changes that we don't expect to the
bottles that we create.

tests/formulae_dependents: do not `brew link` keg only formulae

`unlink_conflicts` skips keg-only formulae, so trying to `brew link`
these formulae can result i...

tests/formulae: add cached formulae to `@built_formulae`

Without this we risk skipping builds of dependents of just-built
formulae in a PR.

formulae_dependents: cache dependent testing results

This will allow us to speed up dependent testing in PRs that touch
multiple formulae.

Will also...

tests/formulae: simplify fix

The earlier fix also wasn't quite correct, since `tap` can be `nil`.
This is much simpler and ha...

tests/formulae: fix Homebrew/brew tests (again)

`before` will be a SHA1 for Homebrew/brew, but `repository` points to
`Homebrew/core`, so trying...

tests/formulae: fix failing `Homebrew/brew` tests

These are run without Homebrew/core checkouts. Let's avoid failing
those.

formulae: ignore API authentication failures when downloading bottles

tests/formulae: do not call `failed` in a dry run

Returning early from `bottle_reinstall_formula` is expected for a dry
run.

The most likely cause for this is use in a repo that isn't
Homebrew/core. See, for example, Home...

This is needed to avoid

This should help simplify this workflow a bit.
