## OpenReader v1.2.7 — Phase 1 Windows Integration

### Windows file integration
OpenReader now appears under **Open with**
OpenReader now appears in **Default apps**
`.pdf` file-association registration is corrected (MSIX `windows.fileTypeAssociation` + Inno `ChangesAssociations=yes`)
Opening additional PDFs routes them into the existing OpenReader instance
Improved handling for paths with spaces, Unicode filenames, parentheses, and long paths

### Default PDF reader experience
First-launch default-reader prompt (Set as default / Maybe later / Do not ask again)
Settings section for PDF defaults (**File → Settings → Files / Default Apps**)
Accurate detection of OpenReader as the current default (ownership resolved via the registered open command / AppUserModelId across HKCU + HKLM)
Direct access to Windows Default Apps
No silent takeover of Windows defaults

### Store-aware updates
Microsoft Store / MSIX installs use the Store update experience (Open Microsoft Store, no GitHub redirect)
GitHub / Inno installs retain GitHub release checks
Portable and development installs receive appropriate update handling
Improved offline behavior (clean error message + Try Again)
Persisted skip-version support

### Maintenance
Version-source alignment (single source of truth: `main.py`, MCP package metadata, MSIX manifests)
Changelog cleanup
Improved packaging tests
Expanded Windows integration and path-handling coverage
