docs: update CLAUDE.md to use Bash-compatible commands

- Replace all PowerShell code blocks with bash
- Update platform description from "Windows with PowerShell" to "Cross-platform (Linux/macOS/Windows with WSL or Git Bash)"
- Change Dapr CLI installation to use wget/curl instead of PowerShell invoke-webrequest
- All commands now work on Linux, macOS, and Windows with WSL/Git Bash

Ensures consistency with cross-platform development and CI/CD environments.
