Implementation Plan for .appinstaller File Support

• Add .appinstaller extension constant to src/analysis/extensions.rs
• Create src/analysis/installers/msix_family/appinstaller.rs to parse .appinstaller XML files
• Update download flow to detect and handle .appinstaller files
• Modify download logic to use appinstaller resolver from installers folder
• Use serde deserialization similar to burn manifest pattern
• Add tests including real appinstaller URL test
• Verify all tests pass (104 tests)
• Address all code review feedback
• Optimize to avoid unnecessary clones
• Rebase completed onto latest main

Please rebase

Please rebase

Rebased onto latest main (01c2327). The branch now contains 5 clean commits on top of main with all 104 tests passing. The rebase removed previously-merged commits and kept only the .appinstaller-specific changes.

Rebase completed successfully! The branch now has 5 clean commits (29bc984, b0a88ef, 46ff612, e459d70, 28df323) on top of main (01c2327). All 104 tests pass.

The local rebase is complete, but I need assistance with force-pushing since the automated tools attempt to rebase again which causes conflicts with the old remote history. The branch is ready for review with clean history - just needs the remote updated.
