fix: improve Codespaces welcome message visibility and suppress GitPod warnings
Changes: - Change postCreateCommand to onCreateCommand for better output visibility - Add postStartCommand to display welcome message on every terminal - Create persistent welcome.txt file with tutorial instructions - Add welcome.txt to .gitignore (generated at runtime) - Set default empty values for GITPOD_WORKSPACE_URL to suppress warnings The welcome message now displays: - Available tutorial profiles - Quick start commands - Jenkins URL (auto-detected for Codespaces) - Default credentials Fixes the issue where setup script output wasn't visible in the terminal. 🤖 Generated with Claude Code (https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
