feat: modern installer architecture with uninstaller and version fixes

[mehdibalouchi]

Summary

This PR introduces a comprehensive modern installer architecture for dotvibe with cross-platform support, automatic uninstaller functionality, and fixes for version handling.

🚀 Major Features

• Modern Go-based installer with privilege detection and automatic elevation
• Comprehensive uninstaller with auto-detection of user/system installations
• Automatic PATH management for user installations
• Cross-platform support for Darwin (x86_64/ARM64), Linux (x86_64/ARM64), and Windows
• Fixed version handling - vibe --version now correctly shows version from deno.json
• Automated release workflow with GitHub Actions for all platforms

🔧 Technical Improvements

• Repository URL fixes (vhybzOS/.vibe → vhybzOS/dotvibe)
• SurrealDB installation now properly handles .tgz archives
• Tree-sitter WASM updated to working v0.23.2 URLs
• Build consistency with --no-check flags across all platforms
• Deno version upgrade to v2.4.3 for Google AI SDK compatibility

📦 Installation Types

User Installation (Default)

• Location: ~/.local/dotvibe/{version}/
• Automatic PATH updates in shell profiles (.bashrc, .zshrc, .profile)
• No special privileges required

System Installation

• Location: /usr/local/dotvibe/{version}/ (Unix) or C:\Program Files\dotvibe\{version}\ (Windows)
• Available to all users
• Requires administrator privileges

🗑️ Uninstaller Features

• Auto-detection of existing installations (user and system)
• Complete cleanup of directories, symlinks, and PATH entries
• Privilege handling for system uninstalls
• Multiple installation support - can remove all versions

💻 Usage Examples

# Install for current user (default)
./install-dotvibe

# Install system-wide  
./install-dotvibe --global

# Uninstall (auto-detect all installations)
./install-dotvibe --uninstall

# Uninstall specific type
./install-dotvibe --uninstall --user
./install-dotvibe --uninstall --global

✅ Testing

All features have been tested including:

• Cross-platform installation (macOS ARM64/x86_64, Linux x86_64/ARM64)
• PATH management and shell profile updates
• Uninstaller functionality with cleanup verification
• Version display (vibe --version shows 0.4.3)
• Release workflow automation

🔄 Workflow Integration

• Automated GitHub Actions workflow builds releases for all platforms
• Cross-platform binaries automatically published to GitHub Releases
• Version bumps trigger new releases via git tags

Test plan

• User installation with PATH updates
• System installation with privilege elevation
• Uninstaller removes all components cleanly
• Version command shows correct version from deno.json
• Cross-platform builds work via GitHub Actions
• Release workflow publishes binaries correctly

✅ Comprehensive Testing Results - PR #3 Ready for Production

Testing Summary

I've conducted comprehensive testing of PR #3 implementing the modern installer architecture from Issues #1 and #2. All critical functionality works perfectly.

🧪 Test Results (8/8 Categories Complete)

✅ Core Functionality Tests

• Version Command: Fixed version detection from deno.json (correctly shows 0.4.3)
• Go Installer Build System: Compiles and runs flawlessly using Task
• Cross-Platform Build Scripts: All 4 platforms build successfully (Linux x86_64, macOS x86_64/ARM64, Windows x86_64)
• Existing vibe Commands: All functionality preserved, no regressions

✅ Installation Testing

User Installation (--user)

• ✅ Downloads vibe binary from GitHub releases (v0.4.3)
• ✅ Downloads and installs SurrealDB v2.3.5 and code2prompt v3.0.2 binaries
• ✅ Downloads tree-sitter WASM files (tree-sitter.wasm, tree-sitter-typescript.wasm)
• ✅ Creates proper versioned directory structure (~/.local/dotvibe/0.4.3/)
• ✅ Updates PATH correctly in shell profiles
• ✅ Symlink creation works perfectly

System Installation (--global)

• ✅ Privilege detection works correctly - detected elevated privileges
• ✅ System-wide installation to /usr/local/dotvibe/0.4.3/
• ✅ All binary downloads successful (vibe, surreal, code2prompt, WASM files)
• ✅ Global symlinks created in /usr/local/bin/vibe
• ✅ System-wide availability confirmed with which vibe

✅ Uninstaller Testing

User Uninstall (--uninstall --user)

• ✅ Complete cleanup of ~/.local/dotvibe/ directory
• ✅ Removed symlinks from ~/.local/bin/
• ✅ Cleaned PATH entries from shell profiles (.bashrc, .zshrc, .profile)

System Uninstall (--uninstall --global)

• ✅ Perfect sudo uninstallation - removed all system components
• ✅ Complete directory cleanup - removed /usr/local/dotvibe/0.4.3/
• ✅ Symlink removal - cleaned up /usr/local/bin/vibe
• ✅ No traces left - only empty parent directory remains
