🚀 v0.6.0 — Unified Installation Architecture

This release introduces a complete refactoring of the installation system, consolidating separate installers into a unified, intelligent installer with automatic detection and interactive workflows.
It focuses on code simplification, user experience, and installation reliability.

🔧 Installation System

/install.sh (Completely Refactored)

Added

• 🔄 Complete refactoring into unified installer (replaces separate install.sh and new-install.sh)
• 🤖 Interactive installation mode with automatic detection of existing installations
• 📋 Menu-driven workflow: [1] Update (preserves data) [2] Reinstall (fresh) [3] Cancel
• 🚀 Flag --reinstall to force complete reinstallation bypassing interactive menu
• 🔍 Flag --verbose for detailed output during installation operations
• ✂️ Eliminated ~500 lines of duplicate code through consolidation
• ✅ Enhanced backup verification with file count comparison before removal
• 🔐 Verification of .git directory existence after clone to ensure completeness
• 🎯 Single code path eliminates synchronization issues between separate installers
• ⚙️ Conditional behavior based on IS_UPDATE flag for precise control flow
• ⏱️ Improved timing for dev branch confirmation (after user selects action)
• 🌿 Branch selection support: add -- dev parameter to install development branch
• 🔗 Dynamic GitHub URL generation based on selected branch
• ⚠️ User confirmation prompt when installing dev branch (with cancel option)
• 🔎 Remote branch existence verification as first operation (before system checks/dependencies)
• 🏷️ Branch verification after git clone with mismatch warning
• 📺 Branch display in installation banner with dev warning

Fixes

• 🔍 Branch existence check now uses grep -q "refs/heads/$branch" for reliable validation
• 🚫 Prevents false positives when checking if remote branch exists
• 🛡️ Consistent error handling and logging across all installation scenarios
• 🧹 Proper cleanup of temporary artifacts on failure or cancellation
• 🔧 Modified git clone to use -b "$INSTALL_BRANCH" flag
• 🔗 Updated all hardcoded /main/ URLs to use ${INSTALL_BRANCH} variable

Behavior

• 🎯 Default mode: Detects existing installation and presents interactive menu
• 🔁 With --reinstall: Forces complete reinstallation without interactive prompts (except REMOVE-EVERYTHING)
• 📊 With --verbose: Shows detailed output from apt, git, and tar operations
• 🌿 Full branch selection support (main/dev) works in all modes
• 💾 Automatic preservation of user data during updates: env, config, log, backup, lock directories

Deprecation Notice

• ⚠️ new-install.sh is now deprecated and replaced by install.sh --reinstall
• 🔄 The refactored install.sh now handles both update and reinstall scenarios
• 📢 Users calling new-install.sh should migrate to install.sh --reinstall

Migration Path for new-install.sh users

• 🔄 Replace new-install.sh calls → install.sh --reinstall
• 🌿 Branch selection unchanged: -- dev parameter works with all modes
• ⬆️ Old install.sh behavior (update only) → New install.sh default behavior (auto-detect + interactive menu)
• 🔁 Old new-install.sh behavior (forced reinstall) → New install.sh --reinstall behavior

✅ Overall Improvements

• 🎯 Single, unified installation system eliminating code duplication
• 🤖 Intelligent auto-detection of existing installations with interactive workflows
• 🌿 Full branch selection support (main/dev) across all installation modes
• 🔍 Enhanced validation and verification at every installation step
• 📊 Improved user experience with clear menu-driven choices
• 🛡️ Better error handling and recovery mechanisms
• 🧹 Cleaner codebase with ~500 fewer lines of duplicate code

✨ Result: A streamlined, reliable installation experience with intelligent detection, safer upgrades, and flexible branch support—all in a single, maintainable codebase.
