This PR (12/12): installer repackage, qualification scripts, CI workflow, docs rewrite

Commits:

• 927f49c build: repackage the installer around the native runtime — installers/muesli-windows.iss, scripts/package-windows-v1.ps1, scripts/install-windows.ps1, scripts/uninstall-windows.ps1
• 6b5d00a test: model smoke tests and native runtime setup scripts — scripts/smoke-transcription-models.ps1, scripts/install-parakeet-cuda-runtime.ps1
• 66f0955 test: dictation accuracy and latency qualification scripts — scripts/qualify-dictation-corpus.ps1, scripts/qualify-dictation-target.ps1, scripts/qualify-dictation-target-suite.ps1, scripts/summarize-dictation-latency.ps1, scripts/test-transcription-corpus.ps1
• c28fa90 test: meeting lifecycle, media import and release qualification scripts — scripts/qualify-meeting-session-lifecycle.ps1, scripts/qualify-windows-release.ps1, scripts/test-media-imports.ps1, scripts/test-windows-package.ps1, scripts/fresh-machine-qa.ps1, scripts/sign-windows-release.ps1, scripts/verify-phase12-ui.ps1, scripts/benchmark-native-*.ps1
• 5350416 ci: Windows build, test and package workflow — .github/workflows/windows-ci.yml
• 8620e93 docs: rewrite architecture docs for the native pipeline — README.md, windows-native/README.md, docs/ (ROADMAP, WINDOWS_NATIVE_PLAN, WINDOWS_V1_RELEASE, TRANSCRIPTION_BENCHMARKS, qualification guides, PHASE8_CONTEXT_TRANSFER, WINDOWS_STREAMING_ASR_INVESTIGATION, WINDOWS_TRANSCRIPTION_MODELS)

34 files, +3,325/−438.

Review focus

• installers/muesli-windows.iss + scripts/package-windows-v1.ps1 — native-runtime payload layout, CUDA runtime optional component, no Python anywhere in the package.
• .github/workflows/windows-ci.yml — build → 484-test run → package chain; first real run happens on this PR.
• Qualification scripts — these are the human gates referenced throughout the series (dictation accuracy/latency, meeting lifecycle, media import, fresh-machine QA, release qualification).
• docs/ROADMAP.md + docs/WINDOWS_V1_RELEASE.md — the post-review plan, including the deferred items (D1/D3/D4/D5).

Divergence note (see PR 1 for full context): after this stack was cut, main dropped Inno Setup in favor of Velopack. This PR repackages Inno. The packaging end-state is the one open decision of this series and is deferred to merge time — Velopack would additionally deliver the real auto-updater (roadmap D5).

Known limits

• Installer is unsigned (external certificate blocker); scripts/sign-windows-release.ps1 is ready for when a cert is available.
• Fresh-machine CPU-only and NVIDIA qualification runs are still pending (scripts provided).
• Physical DPI/multi-monitor evidence: see PR 8 Known limits.

Test evidence

• dotnet build windows-native\Muesli.Windows\Muesli.Windows.csproj --no-restore — clean
• dotnet test windows-native\Muesli.Windows.Tests\Muesli.Windows.Tests.csproj --no-restore — 484/484 passing (suite from PR 11)

Pull request overview

This PR finalizes the Windows-native pipeline by repackaging the release artifacts around the native sherpa-onnx runtime (no Python/venv/worker), adding human/automated qualification scripts and a first Windows CI workflow, and rewriting docs to reflect the native runtime + qualification gates.

Changes:

• Repackages the ZIP/installer payload and adds package QA to enforce “no Python” + native runtime integrity.
• Adds PowerShell qualification/benchmark harnesses for dictation, meeting lifecycle, media import, and release gating.
• Introduces a Windows GitHub Actions workflow to build/test/package and smoke-test the produced ZIP; refreshes docs/READMEs accordingly.
