This is necessary for an incremental migration to `rules_js` which
requires Bazel v6. Bazel v6 removed the managed directories feature,
which means we no longer can rely on symlinked node modules as the Bazel
repository; but rather need to duplicate dependencies. This is
okay/acceptable to enable the incremental migration.
This also requires us to move patches from `patch:` protocol to
`patch-package` temporarily. This is because we need to temporarily use
pnpm and yarn berry in hybrid, and both don't have any overlap in how
patching works; and pnpm would fail if it sees the `patch` protocol.
This commit sets up `rules_ts`, providing the `ts_library` equivalent
for the `rules_js` migration.
This commit introduces a new interop Starlark macro/rule for using
`ts_project` throughout the repository without having to migrate
any dependant or dependencies; allowing for incremental migration
to `ts_project`.
This is necessary as the current rule is not clever enough to detect
when a given file is already "generated" and inside `bin`.

This is important because `package.json` files are always copied to bin
for `npm_package`, but the `package.json` may already be copied from
e.g. `ts_project#data`. This shouldn't cause a Bazel action conflict.
This commit updates the architect devkit package code to use
`ts_project`. We specificially don't migrate the jasmine node test yet
as we want to experiment further with the incremental migration.
It seems that the chunk deterministic name has changed after
recent node module /lock file changes. It's unclear what specifically is
involved in Webpack's chunk name generation, but the output and all
other tests still look good; which makes this is a rather safe update to
the new chunk name. Consulting with CLI team members explained that this
can happen quite often.
… setup

- it seems to be disabled by default for actual production .ts files;
  but the rule is in "error" mode for spec files.
- The rule doesn't seem to properly support mono-repos when configured properly.
i.e. it only considers the top-level package.json — hence doesn't deal with cross-workspace deps.
Workaround until `rules_js` imports the latest version of
`aspect_bazel_lib`: bazel-contrib/bazel-lib#968
In our dev-infra sync we decided that we want to have less
ambiguous naming for node modules from the workspace root vs. node
modules that are local to the package.

Consider the confusion between: `//:node_modules` and `:node_modules`.
This commit fixes this by naming the workspace `node_modules` as
`:root_modules`. This does not have an effect on runtime of NodeJS
output because `rules_js` continues to lay out the root modules as
`/node_modules` folder; as it should.
I suspect there were some versioning changes with the e.g. `hoist =
false` setting in npmrc; so eslint now starts failing about this
unnessary type cast. Seems reasonable so this is committed without
deep investigation.
…nt error

I suspect there were some versioning changes with the e.g. `hoist =
false` setting in npmrc; so eslint now starts failing about an import
from `webpack-server.ts` resulting in unnecessary type cast lint errors.

The existing mapping didn't work due to the underscore conversion, so
this makes sense, and fixing the path mappings works.

Is this something we would like to have "permanently" in this config?

There should be a TODO to remove if you're hinting at this 😄
