This uses the [boneskull/nodejs-production-test-action](https://github.com/boneskull/nodejs-production-test-action) GH action to run a smoke test across all packages.
The action does the following:
1. Runs `npm pack` on each package, writing the tarball to a temp dir. This tarball contains the package as a user would `npm install` it.
2. Changes into the temp dir and runs `npm install <tarball>` on each
3. Runs a specified script (in our case, `test:smoke`) in each installed package's dir in `<tmp_dir>/node_modules`
Because `devDependencies` will not be present, this should avoid a class of issues where production deps are miscategorized as dev deps.
The action should probably use a separate temp dir for each--in the case of a dependency being present but only because some other package depends on it--but it's not smart enough to figure out peer dependencies yet.
Resolves#16924
Because the `postinstall` script of `appium` needs functions in `@appium/support`, that module must be compiled _before_ its `postinstall` script runs. Prior to this PR, only the monorepo root would run a `postinstall` script to build the subpackages. Now, each package has a `prepare` script which runs its own build; this happens prior to any `postinstall`. This way, the `postinstall` script in `appium` can run successfully.
`@appium/schema` is a package which was extracted from `appium`. It _only_ contains the schema. The impetus here was to avoid cyclical dependencies, since `appium` depends on `@appium/types`, and `@appium/types` depends on the schema. This package breaks the cycle.
The `scripts/generate-schema-json.js` (which converts the compiled JS schema file into JSON) has moved into this package, and the generated JSON file is now under version control. This is because the `generate-schema-types.js` script (previously `generate-schema-declarations`) depends on it, and `@appium/types` depends on the generated types. The generated types are _also_ under version control. I do not expect the schema to change often, so I believe the tradeoff to be worth it.
## @appium/schema
`lib/appium-config-schema.js` is the "single source of truth" for the schema.
## appium
- Removed schema source
- Removed namespaces from internal types because they suck (see change to `types/index.d.ts`)
- Removed unused `continuation-local-storage`
- Add dep for `@appium/schema`
- Added a TS project dependency on `@appium/schema`
## @appium/types
- The "sources" have moved from `src` to `lib` for consistency.
- `lib/appium-config.ts` (the generated types) are now under version control.
- `lib/schema/` has been removed (it previously held the JSON schema artifact)
- `scripts/generate-schema-declarations.js` becomes `scripts/generate-schema-types.js`
- Updated scripts in `package.json`
- Added dep for `@appium/schema`
- Added a TS project dependency on `@appium/schema`
## Other
- Reorganize root `tsconfig.json`; add `schema` reference; remove unused `noEmit: true`
- Sort root `package.json`
- Remove schema JSON and schema declarations scripts, since those are now both handled in their respective packages
- Remove `lint-staged` config for schema file, since it didn't work right anyway (still need to do something about this, but probably doesn't need to be in a precommit hook)
- Remove stuff from `.gitignore`
