Clusterio #984 converted its packages to ESM, so a CommonJS plugin can
no longer import @clusterio/lib and plugin entrypoints must name the
full file. Every package gets "type": "module", entrypoints and relative
imports carry the .js extension, and the webpack configs become .cjs as
webpack-cli loads them with require. tsconfig.node.json moves from
node16 to nodenext to match clusterio, which needs it for the JSON
import attributes in its sources.
The tap tests and the shared test helpers use import and
import.meta.dirname. The test scripts pass --type-strip-only so tap
leaves lib's .ts subpath imports to Node's own type stripping, as its
TypeScript loader compiled them without a default export. The lua
runner resolves fengari from the test file it is given, since a bare
import from the shared test directory does not reach the plugin's
devDependencies.

- The generic parts move to test/ in the repository root so other plugins can
reuse them: the factorio and clusterio stubs, the test framework, the
fengari runner, and clusterio's testMatrix and round trip helpers. A plugin
composes them from its own env.lua, which adds its stubs and fixtures.
- Tests are declared with Test.test(name, fn) and every test function
receives a fresh environment, so nothing carries over between them. A test
which errors is reported as a failure rather than aborting the file.
- Every stub raises on properties it does not implement, which mirrors the
game api. game.player is the one property allowed to read as nil.
- Test.deep_eq compares tables recursively with keys checked from both sides.
- The message records round trip through the same testMatrix and
testRoundTripJsonSerialisable helpers the clusterio tests use, covering
every optional field combination of the records, events and requests.
- controller.test.js and instance.test.js cover the node side of the plugin
against faked controller and instance internals: property creation and
sweeping, record building, broadcasts, subscription replay, assignment
validation, auto assignment and its blocking role, seeding, the initialise
payload, sync mode gating, and the rejection rollback.
