feat(refactor): Unify tsup configs, gulp -> tsup

[rossbulat]

This PR refactors the build setup across multiple packages by replacing Gulp with a unified tsup configuration and simplifying the builder logic.

• Removed legacy gulpfile.js in several libraries (observables-connect, hooks, factories) and introduced/updated tsup.config.ts in hooks, factories, and crypto.
• Standardized tsconfig.json (rootDir: "."), updated pkg.config.json to set "bundler": "tsup" and fix export paths, and bumped package versions and devDependencies.
• Simplified the builder tool by removing explicit bundler parameters, unifying generatePackageJson and simpleBuild signatures, and dropping Gulp handling.

library/observables-connect/gulpfile.js:1

• The Gulp build file was removed but no replacement tsup.config.ts or updated build script was added for observables-connect, so its build will break. Please introduce a tsup config and adjust its package.json accordingly.

library/extension-assets/package.json:30

• There is no build script defined here, but simpleBuild invokes pnpm build and will fail. Please add a build script (e.g., using tsup or a copy step) or update the builder to skip the build step for this package.
