release: v1.0.20 -- inert trigger release for v1.0.19 dot-bg-fix smoke

DEPRECATED: this release is defective. Use v1.0.27 instead.

No release from v1.0.7 through v1.0.26 produces an installable Standard-mode ISO. This version crashes the Standard-mode build at 18% -- the autounattend binding references catalog item tweak-compact-install, which was never added to catalog.json; v1.0.8 turned that missing id from a silent default into a hard error.

v1.0.27 reverts the image-shaping build pipeline to the proven v1.0.6 code -- verified end-to-end (clean build, clean install, Compact OS on, first-boot cleanup working) -- while keeping the post-v1.0.6 UI, logging, and failed-build cleanup. Existing installs auto-update via Velopack. Core-mode builds were unaffected.

---

No-op smoke-trigger release. Zero behavior change vs v1.0.19. Sole purpose: be the "newer release" that a v1.0.19-installed launcher detects via its (v1.0.13-added) window.focus re-check, so the v1.0.19 dot-bg fix can be smoked end-to-end. Expected on v1.0.19 badge surface: resting blue pulsing dot (both themes); hover dark = solid white dot at center + white wave fading outward; hover light = solid #3a3a3a dot at center + #3a3a3a wave fading outward; tooltip "Update available, click to install..." renders steady. The "nav bg shows through the dot" bug from v1.0.17/v1.0.18 is gone.

Changed

• launcher/tiny11options.Launcher.csproj — <Version>1.0.19</Version> → <Version>1.0.20</Version>.
• launcher/app.manifest — assemblyIdentity version="1.0.19.0" → "1.0.20.0".

No code, resource, or test changes. Pester 516/0 + xUnit 140/0 both expected to match v1.0.19 ship.

Note

• v1.1.0 = Microsoft Trusted Signing (unchanged from v1.0.18 breadcrumb).
