feat!: TypeScript rewrite with dual-format build, automated releases, lint, and demo

BREAKING CHANGE: package now ships compiled dist/ instead of raw source.
Consumers importing from the package root directly must update to use the
published dist/ output.

- Move source to src/index.tsx, tests to __tests__/
- Add tsup build (CJS + ESM + .d.ts), dual exports map in package.json
- Add semantic-release with beta prerelease channel support
- Add ESLint (typescript-eslint, react, react-hooks) + Prettier + Husky pre-commit
- Add CI, Release, and Deploy Demo GitHub Actions workflows
- Add Vite + react-native-web demo deployed to gh-pages
- Update README and add CONTRIBUTING.md

+## Conventional Commits
+
+This project uses [Conventional Commits](https://www.conventionalcommits.org/) to automate versioning and changelog generation via `semantic-release`.
+
+Every commit message must follow this format:
+
+```
+<type>(<optional scope>): <description>
+```
+
+### Commit types and their effect on versioning
+
+| Type       | Description                    | Release            |
+| ---------- | ------------------------------ | ------------------ |
+| `feat`     | A new feature                  | Minor version bump |
+| `fix`      | A bug fix                      | Patch version bump |
+| `perf`     | A performance improvement      | Patch version bump |
+| `chore`    | Maintenance / tooling          | No release         |
+| `docs`     | Documentation only             | No release         |
+| `refactor` | Code change, no feature or fix | No release         |
+| `style`    | Formatting, whitespace         | No release         |
+| `test`     | Adding or updating tests       | No release         |
+| `ci`       | CI/CD changes                  | No release         |
+| `build`    | Build system changes           | No release         |
+
+### Breaking changes
+
+A breaking change triggers a **major version bump** regardless of the commit type. Indicate it in one of two ways:
+
+**Option 1 — `!` suffix on the type:**
+
+```
+feat!: remove deprecated myRef prop
+```
+
+**Option 2 — `BREAKING CHANGE` footer:**
+
+```
+feat: remove deprecated myRef prop
+
+BREAKING CHANGE: The `myRef` prop has been removed. Use the standard `ref` prop instead.
+```
+
+### More examples
+
+```
+feat: add support for placeholder color prop
+fix: label stays in dirty position after clear()
+chore: upgrade tsup to v9
+docs: update README installation steps
+```
+
+## Development workflow
+
+```bash
+# Install dependencies
+npm install
+
+# Run tests
+npm test
+
+# Type-check
+npm run type-check
+
+# Build the library
+npm run build
+
+# Start the demo dev server (http://localhost:5173)
+npm run demo
+```
+
+## Submitting changes
+
+1. Fork the repository and create a branch from `master`.
+2. Make your changes, following the Conventional Commits format for every commit.
+3. Ensure `npm test`, `npm run type-check`, and `npm run build` all pass locally.
+4. Open a pull request against `master`. The CI workflow will run automatically.
+
+## Setting up NPM_TOKEN for automated publishing
+
+Automated npm publishing is handled by `semantic-release` via the `release.yml` workflow. It requires a `NPM_TOKEN` secret in the GitHub repository settings.
+
+**Steps to configure:**
+
+1. Log in to [npmjs.com](https://www.npmjs.com) and go to **Access Tokens** in your account settings.
+2. Click **Generate New Token** and choose **Granular Access Token** (or Classic → **Automation** type).
+3. Grant the token **read and write** access to the `react-native-floating-labels` package.
+4. Copy the generated token.
+5. In the GitHub repository, go to **Settings → Secrets and variables → Actions**.
+6. Click **New repository secret**, name it `NPM_TOKEN`, and paste the token value.
+
+The `GITHUB_TOKEN` secret is automatically provided by GitHub Actions and requires no manual setup.
+
+## Releasing
+
+Releases are fully automated. When a PR is merged to `master`:
+
+1. The `CI` workflow runs tests, type-check, and build.
+2. On success, the `Release` workflow runs `semantic-release`.
+3. `semantic-release` analyzes commits since the last release, determines the next version, publishes to npm, creates a GitHub release, and commits an updated `CHANGELOG.md` back to `master`.
+
+You do **not** need to manually bump versions or tag releases.
