feat(frontend): migrate from npm/lerna to bun/turborepo/changesets

- Replace lerna with changesets for version management and npm publishing
- Migrate from npm to bun as the package manager
- Add bun.lock and remove package-lock.json
- Add changeset scripts: changeset:add, changeset:version, changeset:publish
- Delete lerna.json
- Update .gitignore to exclude package-lock.json

Benefits of this migration:
- Bun: ~10x faster package installs, native TypeScript support
- Turborepo: Intelligent caching for builds (already added)
- Changesets: Cleaner workflow for version management and publishing

+# Changesets
+
+This folder is used by [Changesets](https://github.com/changesets/changesets) to manage versioning and changelogs for the Superset frontend packages.
+
+## How to add a changeset
+
+When you make changes to packages that should be published, run:
+
+```bash
+npx changeset
+```
+
+This will prompt you to:
+1. Select which packages have changed
+2. Choose the semver bump type (major/minor/patch)
+3. Write a summary of the changes
+
+A markdown file will be created in this folder describing your changes.
+
+## Releasing
+
+To create a new release:
+
+```bash
+# 1. Update versions and changelogs based on changesets
+npm run changeset:version
+
+# 2. Build all packages
+npm run turbo:build
+
+# 3. Publish to npm
+npm run changeset:publish
+```
