* feat: add ambient module stubs for declaration generation

Provide TypeScript ambient declarations for 'message_keys' (Pebble SDK
module) and './tmp/config-page.html' (build artefact) so tsc can resolve
these imports when generating .d.ts files.

* feat: add tsconfig for declaration generation

Configures tsc --allowJs --emitDeclarationOnly to generate per-file
.d.ts reference output in dist-types/ from the library source files.

* feat: add curated TypeScript declarations for public API

Hand-curated index.d.ts covering Clay, ClayConfig, ClayItem, ClayEvents,
manipulators, and all supporting types. Necessary because tsc cannot
infer the ClayEvents mixin or dynamically-bound manipulator methods.
All types are exported via the Clay namespace.

* test: add type-checking verification for index.d.ts

Exercises the full public API surface — constructor, instance/static
methods, ClayConfig/ClayItem event methods, manipulator methods,
namespace-exported types, and customFn this-context.

* build: add typescript devDependency, types field, and build scripts

Adds typescript 6.0.2 as a devDependency. Sets "types": "index.d.ts"
in package.json. Adds build:types and check:types scripts.

* build: add gulp types task to validate declarations on build

Validates index.d.ts against test/type-checks.ts as part of the default
gulp build. Reference declaration generation via build:types remains
available as a separate manual step.

* chore: update ignore files for TypeScript declarations

Add dist-types/ to .gitignore (build artefact). Whitelist index.d.ts
in .npmignore so type declarations ship with the package.

* ci: add typecheck workflow to validate TypeScript declarations

Runs npm run check:types on push and PR to main, matching the existing
lint/test/build workflow pattern.

+# Contributing
+
+Thanks for checking out Clay. We accept pull requests from anybody, however we ask
+that you follow some conventions when contributing to Clay.
+
+We have set up a
+[piece-of-cake](https://github.com/pebble-dev/clay/issues?q=is%3Aopen+is%3Aissue+label%3Apiece-of-cake)
+label in GitHub issues for bugs/features that are easy to implement. These issues are
+a great place to start for people that are new to the codebase.
+
+
+## Requirements
+
+ - [Node](https://nodejs.org) (4.0 and later)
+ - [Google Chrome](www.google.com/chrome) (To run tests)
+ - [Pebble SDK](https://developer.rebble.io/sdk/) (optional)
+
+
+## Getting Started
+
+### 1. Fork, then clone the repo:
+
+`$ git clone git@github.com:your-username/clay.git`
+
+### 2. Create a new branch with the following naming convention.
+
+`#<issue-id>/description-of-change`
+
+example:
+
+`#90/support-message-keys`
+
+If there is currently no GitHub issue open for your proposed contribution,
+then please make one. This allows us to assign milestones and triage priority.
+
+### 3. Install the project dependencies.
+
+`$ npm install`
+
+### 4. Develop your feature
+
+Commit as often as you like. Your branch will be squashed when the pull request is merged.
+
+### 5. Run the tests
+
+`$ npm run test`
+
+### 6. Run linting
+
+`$ npm run lint`
+
+### 7. Submit your pull request
+
+In the main comment of the pull request, you must state the GitHub issue that your PR
+resolves. You do this by using the syntax `Resolves #<issue-id>`. An example of this
+can be found [here](https://github.com/pebble/clay/pull/81)
+
+
+
+# Project Structure and Development
+
+
+## Important Files
+
+There are two main entry points for Clay - `index.js` and `src/scripts/config-page.js`.
+
+### index.js
+
+This is the main entry point for the code that will run in the Pebble app's `src/js/app.js`.
+It is responsible for serializing the provided config into a data URI that will be opened
+using `Pebble.openURL()`. It also persists data to `localStorage`.
+
+### src/scripts/config-page.js
+
+This is the main entry point for the code that runs on the generated config page,
+and is responsible for passing the injected config and other components to the
+`ClayConfig` class.
+
+
+## Building
+
+Use the following command to build Clay during development.
+
+`$ npm run dev`
+
+This command packages up `src/scripts/config-page.js` and `dev/dev.js` into the `tmp/` directory
+so `dev/dev.html` can include them as script tags. This will also watch for changes
+in the project.
+
+While developing components and other functionality for Clay, it is much easier to
+work with the files in the `dev/` directory than on a phone or emulator. Below is
+an explanation of the files and their purpose.
+
+| File | Purpose |
+|----------|-----|
+| `dev.html` | Open this page in a browser after running `$ npm run dev`. |
+| `dev.js` | Injects the components and dependencies into the window the same way `index.js` would. |
+| `config.js` | Clay config to use as a sandbox for testing components. |
+| `custom-fn.js` | Clay custom function to be injected by `dev.js`. |
+| `emulator.html` | Copy of the HTML page that is used to make the Clay compatible with the Pebble SDK emulator. |
+| `uri-test.html` | Used to stress test URI creation for older browser versions. |
+
+
+## Testing your change inside of a test project.
+
+Once your change is ready to be tested in the emulator or on the watch, follow these steps:
+
+1. From your Clay fork run `$ npm run pebble-build`. This builds Clay to work with the Pebble SDK
+2. From your test Pebble project, run `$ pebble package install /path/to/your/clay/fork`.
+  This will modify your `package.json` to point directly to your local copy of Clay.
+3. Run the usual`$ pebble build && pebble install --emulator basalt && pebble emu-app-config` to test your modifications
+4. If you make modifications to your fork of Clay, you must repeat the above steps.
+
+
+## Functionality
+
+Most of the magic happens in the `src/scripts/lib` directory. `config-page.js`
+initializes a new instance of `ClayConfig` and calls the injected custom function
+(`window.customFn`) with the `ClayConfig` as its context. This allows developers to
+add extra functionality to the config page, such as setting values of items dynamically
+or registering small custom components.
+
+Once the `ClayConfig` is initialized, we run the `.build()` method. This iterates over
+the config and injects each item into the page. Each item is an instance of `ClayItem`.
+It also indexes the items to later be retrieved with `.getAllItems()`,
+`.getItemByMessageKey()`, `.getItemById()`, `.getItemsByType()`.
+
+
+## Testing
+
+Clay enforces 100% test coverage. Chances are, that if you are submitting a pull request,
+there should be tests for the proposed code changes. Have a look at the other tests in
+the repository to see some examples of how you should be writing your tests.
+
+There are two commands to use while writing your tests.
+
+ - `$ npm run test` - Runs all tests once.
+ - `$ npm run test-debug` - Watches for file changes and re-runs all tests when it
+  detects a change. This also leaves an in instance of Google Chrome running.
+  If you click the "Debug" button in the top right of the page, a new tab will open.
+  You can then use the Google Chrome developer tools to debug your tests as they run.
+  Refreshing the page will re-run the tests.
+
+## Style Guide
+
+Our style guide is very similar to the
+[Airbnb style guide.](https://github.com/airbnb/javascript/tree/master/es5) with the
+following exceptions:
+
+ - When saving a reference to `this` use `self`.
+  ```javascript
+  // bad
+  function() {
+    var _this = this;
+    return function() {
+      console.log(_this);
+    };
+  }
+
+  // bad
+  function() {
+    var that = this;
+    return function() {
+      console.log(that);
+    };
+  }
+
+  // good
+  function() {
+    var self = this;
+    return function() {
+      console.log(self);
+    };
+  }
+  ```
+ - Don't double name your functions. It makes refactoring more difficult.
+
+ ```javascript
+ // bad
+ var log = function log(msg) {
+    console.log(msg);
+  };
+
+ // good
+ var log = function(msg) {
+    console.log(msg);
+  };
+ ```
+
+The style guide is enforced using ESLint. Run `$ npm run lint` to ensure you are
+adhering to the style guide.

+ *  - Strings will be returned without modification
+ *  - Numbers will be returned without modification
+ *  - Booleans will be converted to a 0 or 1
+ *  - Arrays that contain strings will be returned without modification
+ *    eg: ['one', 'two'] becomes ['one', 'two']
+ *  - Arrays that contain numbers will be returned without modification
+ *    eg: [1, 2] becomes [1, 2]
+ *  - Arrays that contain booleans will be converted to a 0 or 1
+ *    eg: [true, false] becomes [1, 0]
+ *  - Arrays must be single dimensional
+ *  - Objects that have a "value" property will apply the above rules to the type of
+ *    value. If the value is a number or an array of numbers and the optional
+ *    property: "precision" is provided, then the number will be multiplied by 10 to
+ *    the power of precision (value * 10 ^ precision) and then floored.
