chore: migrate extension bundler from esbuild to tsup

- Install tsup 8.5.1 and add tsup.config.ts configuration
- Remove esbuild.config.mjs and esbuild devDependency
- Update build scripts in root and src/extension
- Exclude tsup.config.ts in .vscodeignore
- Update VS Code debugging tasks and launch configurations

fix #201
