On an M1 Mac, when running `yarn start`, CPU can spike to 100% CPU, and
sometimes a bunch of `mdworker` instances will get spawned. This seems
to be caused by the file-watching mechanism used in dev to automatically
regenerate the build when something is changed. More specifically, we
are using an older version of `watchify`, which uses an older version of
`chokidar`, which is the package that actually does the watching. v4.0.0
of `watchify` upgrades `chokidar` to v3.x ([1]), which comes with
"massive CPU & RAM consumption improvements" ([2]). After the upgrade,
CPU usage decreases to 20-40%.

The main `version` field in `package.json` will now include the beta
version (if present) rather than it being passed in via the CLI when
building. The `version` field is now a fully SemVer-compatible version,
with the added restriction that any prerelease portion of the version
must match the format `<build type>.<build version>`.
This brings the build in-line with the future release process we will
be using for the beta version. The plan is for each future release to
enter a "beta phase" where the version would get updated to reflect
that it's a beta, and we would increment this beta version over time as
we update the beta. The manifest gives us a place to store this beta
version. It was also important to replace the automatic minor bump
logic that was being used previously, because the version in beta might
not be a minor bump.
Additionally, the filename logic used for beta builds was updated to
be generic across all build types rather than beta-specific. This will
be useful for Flask builds in the future.
* lavamoat - add lavamoat to webapp background
* test:e2e - add delay to resolve failure
* test:e2e - add delay to resolve failure
* build - add a switch for applying lavamoat, currently off for all
* test/e2e - remove delays added for lavamoat
* Revert "test/e2e - remove delays added for lavamoat"
This reverts commit 79c3479f15c072ed362ba1d4f1af41ea11a17d63.
The warnings about use of the unsafe Buffer constructor have been
addressed by package updates and patches.
The updates were:
* `gulp-sourcemaps` was updated from v2 to v3, and was patched to
replace remaining uses of the `Buffer` constructor
* Upstream PR: https://github.com/gulp-sourcemaps/gulp-sourcemaps/pull/388
* The transitive dependency `yazl` was updated from v2.4.3 to v2.5.1
in the lockfile.
* The abandoned packages `combine-source-map` and `inline-source-map`
were patched.
A CI job has been added to ensure the `allow-scripts` config and the
LavaMoat auto-generated policy is up-to-date. This will only run on
release branches and the `master` branch, because it's too difficult a
requirement to meet for each PR for contributors on macOS, due to
differences in the dependency graph caused by optional dependencies.
The `allow-scripts` and LavaMoat policy have both been updated using
`yarn allow-scripts auto` and `yarn lavamoat:auto`.
