This PR adds comprehensive package management capabilities to eget, including package tracking, bulk upgrades, and interactive selection.

📦 Feature 1: Installed Packages Tracking
Store installation metadata in ~/.eget.installed.toml

• Records per-package info: repo, target, installation timestamp, download URL, asset, extracted files, options used
• Tracks version info: Captures tag/version from GitHub API when available
• Enhanced --list-installed: Shows comprehensive package information with current versions
• Smart updates: Records are automatically updated when packages are reinstalled
  Files changed:
• installed.go - New data structures and tracking functions
• flags.go - Added version tracking fields
• eget.go - Integrated recording into installation flow

🔄 Feature 2: --upgrade-all Flag
Bulk upgrade all installed packages with newer versions

• Smart version detection: Uses existing GitHub API integration to check for updates
• Timestamp-based comparison: Leverages release dates for reliable upgrade detection
• Comprehensive reporting: Shows upgrade status for each package (upgrade/skip/error)
• Dry-run support: --upgrade-all --dry-run shows what would be upgraded without changes
• Error resilience: Continues with remaining packages if individual upgrades fail
  Files changed:
• installed.go - Added upgrade checking and bulk upgrade logic
• flags.go - Added --upgrade-all and --dry-run flags
• eget.go - Integrated upgrade flow into main command handling

🎯 Feature 3: --interactive Flag
Beautiful interactive package selection using Bubbletea

• Terminal UI: Multi-select interface with checkboxes and keyboard navigation
• Rich controls:
  • ↑/↓ or j/k: navigate
  • Space: toggle selection
  • a: select all, n: select none
  • ctrl+d/enter: confirm, q/esc: quit
• Smart environment detection: Automatically falls back to non-interactive mode when not in a proper terminal
• Bubbletea integration: Uses Charm's Bubbletea library directly (no external gum dependency)
• Seamless experience: Works with --dry-run for previewing interactive selections
  Files changed:
• go.mod - Added github.com/charmbracelet/bubbletea dependency
• installed.go - Complete Bubbletea model for interactive selection
• flags.go - Added --interactive flag
• eget.go - Integrated interactive parameter into upgrade flow
  🔧 Technical Implementation
  Key Design Decisions:
• TOML-based storage: Uses existing TOML format for consistency
• Backward compatibility: All existing functionality preserved
• Graceful degradation: Features work in automated environments
• Error resilience: Individual failures don't break bulk operations
  Dependencies Added:
• github.com/charmbracelet/bubbletea v1.3.10 - For interactive UI
  🧪 Testing
  All features have been tested with:
• ✅ Package installation tracking and listing
• ✅ Bulk upgrade functionality with dry-run
• ✅ Interactive selection with terminal detection
• ✅ Fallback behavior in non-interactive environments
• ✅ Error handling and recovery
• ✅ Backward compatibility verification
  📚 Usage Examples

List all installed packages with details

eget --list-installed

Upgrade all packages with newer versions

eget --upgrade-all

Preview what would be upgraded

eget --upgrade-all --dry-run

Interactively select packages to upgrade

eget --upgrade-all --interactive

Preview interactive selections

eget --upgrade-all --interactive --dry-run
🔒 Breaking Changes
None. All features are additive and maintain full backward compatibility.

This PR significantly enhances eget's package management capabilities, making it much more user-friendly for managing multiple installed tools. The interactive selection provides a beautiful terminal experience, while the bulk upgrade functionality saves time for users with many packages.
