chore(frontend-readme): clean the readme for frontend (#11955)

* chore: validate layout size and positioning in backend

* test: add integratino test for layout validation

* test: use assert instead of require for non blocking check

* test: use assert instead of require for non blocking check

* fix: move require to assert for actual test checks

+## Local Development Setup
+
+1. Run SigNoz backend locally — see [Self-Host Docs](https://signoz.io/docs/install/self-host/)
+
+2. Configure environment:
+   ```bash
+   cp example.env .env
+   ```
+   
+   Key variables in `.env`:
+   ```bash
+   # Backend API endpoint (required)
+   VITE_FRONTEND_API_ENDPOINT="http://localhost:8080"
+   
+   # Enable bundle analyzer (optional)
+   BUNDLE_ANALYSER="true"
+   ```
+
+3. Install and run:
+   ```bash
+   pnpm install
+   pnpm dev
+   ```
+
+## Development
+
+```bash
+pnpm dev
 ```
 
-```
-docker compose up
+Opens [http://localhost:3301](http://localhost:3301).
+
+## Build
+
+```bash
+pnpm build
 ```
 
-## Without Docker
-Follow the steps below
+Output in `build/` folder.
 
-1. ```git clone https://github.com/SigNoz/signoz.git && cd signoz/frontend```
-1. change baseURL to ```<test environment URL>``` in file ```src/constants/env.ts```
+## Bundle Size Analysis
 
-1. ```pnpm install```
-1. ```pnpm dev```
+Set in `.env`:
+```bash
+BUNDLE_ANALYSER="true"
+```
 
-```Note: Please ping us in #contributing channel in our slack community and we will DM you with <test environment URL>```
+Then run build:
+```bash
+pnpm build
+```
 
-# Getting Started with Create React App
+Opens bundle analyzer visualization automatically.
 
-This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
+## Testing
 
-## Available Scripts
+```bash
+# Unit tests
+pnpm test
 
-In the project directory, you can run:
+# Type checking
+pnpm tsgo --noEmit
+```
 
-### `pnpm start`
+## Linting
 
-Runs the app in the development mode.\
-Open [http://localhost:3301](http://localhost:3301) to view it in the browser.
+```bash
+# Run all linters (oxlint + stylelint)
+pnpm lint
+```
 
-The page will reload if you make edits.\
-You will also see any lint errors in the console.
+## Project Structure

-Launches the test runner in the interactive watch mode.\
-See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
+## Contributing
 
-### `pnpm build`
+See [CONTRIBUTING.md](../CONTRIBUTING.md) in the root repo.
 
-Builds the app for production to the `build` folder.\
-It correctly bundles React in production mode and optimizes the build for the best performance.
-
-The build is minified and the filenames include the hashes.\
-Your app is ready to be deployed!
-
-See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
-
-### `pnpm eject`
-
-**Note: this is a one-way operation. Once you `eject`, you can’t go back!**
-
-If you aren’t satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
-
-Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
-
-You don’t have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
