feat(reader): complete configuration and Windows integration
Add cancel-safe native Settings pages, configurable typography/CSS/themes,
file registration and activation, theme-aware source and proportional layout,
toolbar/footer/editor guidance and open-source credits. Preserve attributed
Darin Kelkhoff document styles and literal passive rendering. Retain verbatim
vendor notices with scoped newline/whitespace preservation; secret, security
and other hooks remain enabled.
Validation: zero-warning Release build, 582 core tests with 100% measured line
coverage, 25 Windows adapter tests, formatting and self-contained publish pass.
Current native/distributed acceptance and source-hover diagnosis remain pending;
no production release-readiness claim.
