[matux]

Description of the change

Updates all example projects to properly reference the local rollbar package and fixes compatibility issues discovered during ESM migration testing.

Changes

Example Infrastructure

• Added examples/README.md documenting all example projects and their purposes.
• Created examples/.gitignore to exclude build outputs and package-lock files.
• Updated react, angular and vuejs3 examples to use local rollbar package ("rollbar": "file:../..")

Compatibility Fixes

Vue.js 3 Example

• Created missing src/assets/main.css file that was causing build failures
• Fixed syntax error in src/rollbar.js (unclosed string)
• Added "module" field to root package.json to support Vite's ES module resolution

No-Conflict Example

• Updated webpack config to exclude dist directory from babel transpilation
• Prevents babel from attempting to process already-transpiled distribution files

Angular Example

• Added "analytics": false to angular.json to prevent CLI from waiting for user input during CI builds

Type of change

• Bug fix (non-breaking change that fixes an issue)
• New feature (non-breaking change that adds functionality)

@waltjones I had to revert the examples/react/dist/main.js and examples/react/dist/bundle.js since now that they use the local package ("rollbar": "file:../.."), the resulting js built includes the entire UMD file for a reason that's not entirely clear to me.

I'm gonna solve this by integrating yalc only for the examples. I'm gonna do this on a separate PR so I can merge this.

So the tests were timing out trying to load those js files.

This wasn't affecting the vuejs3 example because we don't have a test/examples for vuejs3, only react, webpack and universalBrowser.
