Migrate project workflows and scripts to Bun

Replace Node/pnpm toolchain with Bun across CI and repo scripts. Workflows now use oven-sh/setup-bun and run bun install / bun run build / bun test; coverage action now uploads lcov.info. Update README to document Bun-based install, build, test and Biome linting. Update package.json scripts (build, dev, test, release flows), pin @types/bun, remove rimraf, and add clean/dev helpers. Adjust create-sei: add inquirer.d.ts, simplify tsconfig, add tsbuildinfo, change CLI messages and build/dev scripts. Update biome.json VCS and file includes and refresh bun.lock with dependency updates.

 ### Prerequisites
 
-This project uses Yarn 4.7.0 with Corepack for package management. To get started:
+This project uses [Bun](https://bun.sh) for package management and testing. To get started:
 
-1. **Enable Corepack** (if not already enabled):
+1. **Install Bun** (if not already installed):
    ```bash
-   corepack enable
+   curl -fsSL https://bun.sh/install | bash
    ```
 
 2. **Install dependencies**:
    ```bash
-   yarn install
+   bun install
    ```
 
-The correct Yarn version will be automatically used thanks to the `packageManager` field in `package.json` and Corepack.
