[Docs][CI] Rebrand to Symfony Reprise and align with Symfony conventions

- Rename the project to "Symfony Reprise" in the README (the @symfony/reprise npm package name is unchanged).
- Document the Symfony [Scope] commit-message convention in AGENTS.md, replacing the previous Conventional Commits style.
- Drop the changelogithub release workflow and its mention in AGENTS.md: it relied on Conventional Commit prefixes and no longer fits the Symfony release flow.
- Add a CONTRIBUTING guide and a pull request template, adapted from Symfony and Symfony UX to this repository's dual PHP-bundle + assets/ npm-package layout.

+- Commit messages: Symfony style `[<Scope>] <Short description>` — PascalCase scope, imperative mood, capitalized first word, no trailing period; combine scopes as `[A][B]` when a change spans several. E.g. `[Stimulus] Emit forward-slash local controller paths`, `[Docs] Frame Stimulus usage as the Encore experience`, `[CI] Cancel superseded runs with a concurrency group`. This is the convention used across Symfony UX and WebpackEncoreBundle — **not** Conventional Commits (no `feat:`/`fix:`/`chore:` prefixes).
+- Releases: the published npm package lives in `assets/` (`@symfony/reprise`); its `prepublishOnly` runs the `tsdown` build before publish.

+# Contributing
+
+Thank you for considering contributing to Symfony Reprise!
+
+Symfony Reprise is an open source, community-driven project, and we are happy to receive contributions from the community.
+
+> [!TIP]
+> It's a good idea to read [Symfony's Contribution Guide](https://symfony.com/doc/current/contributing/index.html) first.
+
+## Reporting an issue
+
+If you find a bug, have a feature request, or need help, please [open an issue](https://github.com/symfony/reprise/issues).
+
+Please provide as much information as possible, and remember to follow our [Code of Conduct](https://symfony.com/doc/current/contributing/code_of_conduct/index.html) to keep the project welcoming for everyone.
+
+## Contributing to the code
+
+### Forking the repository
+
+To contribute to Symfony Reprise, you need to [fork the **symfony/reprise** repository](https://github.com/symfony/reprise/fork) on GitHub.
+
+```shell
+# With GitHub CLI https://cli.github.com/
+$ gh repo clone <USERNAME>/reprise reprise
+
+# Using SSH
+$ git clone git@github.com:<USERNAME>/reprise.git reprise
+$ cd reprise
+$ git remote add upstream git@github.com:symfony/reprise.git
+```
+
+### Setting up the development environment
+
+- **PHP 8.4 or higher**
+- **Composer**
+- **Node.js 22 or higher**
+- **Corepack**
+- **pnpm 11.10 or higher**
+
+```shell
+$ composer install
+$ corepack enable && pnpm install
+```
+
+> [!IMPORTANT]
+> This repository has a dual structure: a PHP Symfony bundle (`symfony/reprise`) at the root, and an npm package (`@symfony/reprise`) in `assets/`, managed together as a pnpm workspace. Most changes touch only one side, but some (like adding a new option) touch both.
+
+### Working with the PHP bundle
+
+The PHP source lives in `src/`, tests in `tests/`. The bundle follows Symfony's PHP coding standards and the Backward Compatibility promise.
+
+```shell
+# Run the test suite
+$ vendor/bin/phpunit
+
+# Run static analysis
+$ vendor/bin/phpstan analyse
+
+# Fix coding standards
+$ vendor/bin/php-cs-fixer fix
+```
+
+### Working with the assets
+
+The actual bundler plugin (the unplugin for Vite and Rsbuild) lives in `assets/`, written in TypeScript and built with [tsdown](https://tsdown.dev/). These commands run from the repository root:
+
+```shell
+# Build the plugin
+$ pnpm build
+
+# Watch and rebuild on change
+$ pnpm dev
+
+# Run the test suite
+$ pnpm test
+
+# Lint
+$ pnpm lint
+```
+
+For manual end-to-end verification against a real Symfony backend, use the `playground/` app (a full Symfony 7 project that imports the plugin directly from `assets/`):
+
+```shell
+$ npm -C playground run vite:dev
+$ npm -C playground run vite:build
+
+$ npm -C playground run rsbuild:dev
+$ npm -C playground run rsbuild:build
+```
+
+### Commit messages
+
+Commit messages follow the same `[<Scope>] <Short description>` convention used across Symfony UX and WebpackEncoreBundle, not Conventional Commits. The scope is PascalCase, the description is imperative mood with a capitalized first word and no trailing period. Combine scopes as `[A][B]` when a change spans several areas.
+
+```
+[Stimulus] Emit forward-slash local controller paths
+[Docs] Frame Stimulus usage as the Encore experience
+[CI] Cancel superseded runs with a concurrency group
+```
+
+## Keeping your fork up to date
+
+To reset your local `main` to match upstream:
+
+```shell
+$ git checkout main && \
+  git fetch upstream && \
+  git reset --hard upstream/main && \
+  git push origin main
+```
+
+To rebase a feature branch on top of `upstream/main`:
+
+```shell
+$ git checkout my-feature-branch && \
+  git rebase upstream/main && \
+  git push -u origin my-feature-branch
+```

 ## Features
 
-⚡️Vite and 🦀Rsbuild already handle **Sass/Less/PostCSS**, **TypeScript**, **JSX/Vue/Svelte**, **code splitting**, **content hashing**, **source maps**, **minification** and **HMR** on their own, so Reprise doesn't reimplement any of that.
