Merge branch 'main' into feat/release-workflow

Rewrites ClaudeDo.Installer to fetch prebuilt binaries from
git.kuns.dev/releases/ClaudeDo instead of building from source.

- Async InstallModeDetector: FreshInstall / Update / Config
- DownloadAndExtractStep with SHA256 verify + scratch-dir extract
- UninstallRunner: stop-service / delete / full ~/.todo-app removal
  with path guard + partial-failure reporting
- Config view: Save / Repair / Uninstall buttons
- Self-contained single-file publish for the installer itself
- 29 xUnit tests in new ClaudeDo.Installer.Tests project

Spec: docs/superpowers/specs/2026-04-15-installer-download-mode-design.md
Plan: docs/superpowers/plans/2026-04-15-installer-download-mode.md
