* 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.
