Add installer build script, docs; tweak UI/theme

Add a PowerShell installer builder (build/build-installer.ps1) and a pre-tag release checklist (docs/plans/PRE_TAG_RELEASE_CHECKLIST.md); update packaging docs to recommend the new script and document Inno Setup theming. Make Inno Setup scripts (Installer/setup.iss and Installer/Installer.iss) more configurable by introducing MyWizardStyle and guarding MyAppBuildDir so WizardStyle can use dynamic Windows theming. Persist system theme preference when the user has no explicit preference (App.xaml.cs and MainWindow.xaml.cs) and switch to IsHitTestVisible for the performance-overlay blur to avoid disabling input globally. Prevent closing the app while the performance intro is visible with a user-facing message. Minor .gitignore cleanup and packaging text updates.

+# ThreadPilot Pre-Tag Release Checklist
+
+Use this checklist before creating a release tag. It is aligned with local build scripts and the GitHub release workflow.
+
+## Release Meta
+
+- [ ] Target version: 1.1.1
+- [ ] Target tag: v1.1.1
+- [ ] Branch is correct for release
+- [ ] Working tree is clean (except intentionally ignored artifact files)
+
+## 1) Artifact Cleanup (Local)
+
+Goal: keep only 1.1.1 artifacts in artifacts/release.
+
+- [ ] Delete old installer: artifacts/release/installer/ThreadPilot_v1.1.0_Setup.exe
+- [ ] Delete old msix: artifacts/release/msix/ThreadPilot_1.1.0.0_win-x64.msix
+- [ ] Delete old zips: artifacts/release/ThreadPilot_v1.1.0_Installer.zip, artifacts/release/ThreadPilot_v1.1.0_Portable.zip
+- [ ] Delete temporary staging dirs: artifacts/release/package-stage, artifacts/release/_stage_installer, artifacts/release/_stage_portable
+
+Expected state:
+
+- [ ] artifacts/release/installer/ThreadPilot_v1.1.1_Setup.exe
+- [ ] artifacts/release/msix/ThreadPilot_1.1.1.0_win-x64.msix
+- [ ] artifacts/release/packages/ThreadPilot_v1.1.1_Installer.zip
+- [ ] artifacts/release/packages/ThreadPilot_v1.1.1_Portable.zip
+
+## 2) Build Gates (Must Pass)
+
+Run from repository root.
+
+Commands:
+
+  dotnet restore "ThreadPilot_1.sln"
+  dotnet build "ThreadPilot_1.sln" --configuration Release --no-restore
+  dotnet test "ThreadPilot_1.sln" --configuration Release --no-build
+
+- [ ] Restore passed
+- [ ] Build passed
+- [ ] Tests passed
+
+## 3) Packaging Gates (Local)
+
+Commands:
+
+  ./build/build-installer.ps1 -Version "1.1.1"
+  dotnet publish "ThreadPilot.csproj" --configuration Release -p:PublishProfile=WinX64-MSIX
+  ./build/package-release-zips.ps1 -Version "1.1.1"
+
+- [ ] Installer generated in artifacts/release/installer
+- [ ] MSIX generated in artifacts/release/msix
+- [ ] Zip packages generated in artifacts/release/packages
+- [ ] Inno Setup warnings target is zero (artifacts/release/installer_iscc_setup.log)
+
+## 4) Naming Gate (Local vs CI)
+
+Local script naming (package-release-zips.ps1):
+
+- [ ] ThreadPilot_v1.1.1_Installer.zip
+- [ ] ThreadPilot_v1.1.1_Portable.zip
+
+GitHub workflow naming (release.yml package step):
+
+- [ ] ThreadPilot_v1.1.1_singlefile_win-x64.zip
+- [ ] ThreadPilot_v1.1.1_readytorun_win-x64.zip
+
+Note: naming differs by channel (local script vs CI workflow). Validate the expected set for the channel you are releasing from.
+
+## 5) Hash + Signature Gate
+
+Generate and verify SHA256 hashes:
+
+Commands:
+
+    $hashFile = "artifacts/release/SHA256SUMS.txt"
+    if (Test-Path $hashFile) { Remove-Item $hashFile -Force }
+
+    $releaseFiles = @()
+    $releaseFiles += Get-ChildItem "artifacts/release/packages" -File -ErrorAction SilentlyContinue
+    $releaseFiles += Get-ChildItem "artifacts/release/installer/*.exe" -File -ErrorAction SilentlyContinue
+    $releaseFiles += Get-ChildItem "artifacts/release/msix" -Recurse -File -Include *.msix,*.appx,*.msixbundle,*.appxbundle -ErrorAction SilentlyContinue
+
+    $releaseFiles | ForEach-Object {
+      $hash = Get-FileHash $_.FullName -Algorithm SHA256
+      "$($hash.Hash)  $($_.Name)" | Out-File -FilePath $hashFile -Append -Encoding utf8
+    }
+
+- [ ] SHA256SUMS.txt generated
+- [ ] Every shipped artifact has one hash row
+
+If signing is enabled:
+
+- [ ] Authenticode signature is valid (Get-AuthenticodeSignature)
+- [ ] Timestamp present (DigiCert or equivalent)
+
+## 6) Smoke Test Installation
+
+Portable smoke test:
+
+Commands:
+
+  $tmp = "$env:TEMP/ThreadPilot_Smoke_$(Get-Random)"
+  Expand-Archive "artifacts/release/packages/ThreadPilot_v1.1.1_Portable.zip" -DestinationPath $tmp -Force
+  Test-Path "$tmp/ThreadPilot.exe"
+
+- [ ] Portable archive extracts correctly
+- [ ] ThreadPilot.exe exists and starts
+
+Installer smoke test:
+
+- [ ] Run artifacts/release/installer/ThreadPilot_v1.1.1_Setup.exe
+- [ ] Install completes without errors
+- [ ] Start menu and/or desktop shortcut launches app
+- [ ] Uninstall path works
+- [ ] Theme is coherent on first launch (system dark -> dark UI + checked setting)
+
+## 7) Pre-Tag Final Gate
+
+- [ ] All gates above are green
+- [ ] Release notes prepared
+- [ ] Optional signing decision documented (signed/unsigned)
+
+Create tag only after all checks pass:
+
+Commands:
+
+  git tag -a v1.1.1 -m "Release ThreadPilot v1.1.1"
+  git push origin v1.1.1
