Prepare v2.0.0 release candidate

[Softhe]

What changed

• Modularizes video configuration, Steam discovery, preferences, and diagnostics.
• Adds privacy-safe diagnostic export.
• Adds GUI regression and isolated packaged-app end-to-end tests.
• Replaces runtime-dependent ZIP creation with a canonical manifest-driven builder.
• Adds optional Authenticode signing tools and stronger release verification.
• Fixes rounded-card repainting so repeated resizing no longer leaves stale border artifacts.
• Updates documentation, release notes, checklist, ZIP, and checksum for v2.0.0.

Why

The prior ZIP builder produced different container bytes under Windows PowerShell
5.1 and PowerShell 7 even though the embedded source matched. The v2 work also
reduces the maintenance risk of the single large script and adds privacy-safe
support diagnostics.

WinForms panels with custom rounded regions did not repaint their full surface
after height changes, leaving previous bottom borders visible. The fix enables
double buffering and full resize redraw and invalidates both the panel and parent.

Validation

• 53/53 Pester tests passed in Windows PowerShell 5.1.
• 53/53 Pester tests passed in PowerShell 7.6.3.
• Repeated-height rounded-card regression passes in both engines.
• Isolated packaged-app flow passed in both engines.
• GUI regression suite passed.
• actionlint 1.7.12 passed.
• Canonical builds were byte-identical across both engines.
• All five packaged runtime files matched repository bytes.
• Final ZIP SHA-256: 740edd0ab11f1eb50ce19e1e85df0c1356345ea0fe956a799f4d7fbb3269cca6.

Release note

Authenticode support is implemented but no trusted code-signing certificate is
installed on the development machine, so signature enforcement is not enabled
in this candidate.

Summary by CodeRabbit

📝 Walkthrough

Walkthrough

The release changes modularize the PowerShell application, add privacy-safe diagnostics and GUI regression coverage, replace single-file packaging with deterministic manifest-driven archives, add artifact and Authenticode verification, and update CI, documentation, and version metadata for 2.0.0.

Changes

Application modules and diagnostics

Layer / File(s)	Summary
Configuration and Steam modules modules/Cs2.VideoConfig.psm1, modules/Cs2.Steam.psm1	Adds resolution/configuration editing, backup and restore handling, Steam discovery, account formatting, and exported module APIs.
Preferences, diagnostics, and launcher modes modules/Cs2.Preferences.psm1, modules/Cs2.Diagnostics.psm1, CS2-VideoConfig-Editor.ps1, tests/Diagnostics.Tests.ps1	Adds persisted preferences, anonymized atomic diagnostics export, module loading, version 2.0.0 metadata, and -ExportDiagnostics validation and execution behavior.

Manifest-driven packaging and artifact validation build/ReleaseFiles.psd1, build/Build-Release.ps1, build/Test-ReleaseArtifacts.ps1, build/Set-ReleaseAuthenticodeSignature.ps1, build/AUTHENTICODE.md	Builds deterministic ZIP32 archives from a validated manifest, checksums and compares packaged bytes, and optionally signs and verifies PowerShell files with Authenticode.
Cross-PowerShell CI and packaged E2E verification .github/workflows/*.yml, build/Invoke-PackagedAppE2E.ps1, tests/Packaged-App-E2E.Tests.ps1	Parses and validates runtime files, compares PowerShell 5.1 and 7 rebuild hashes, smoke-tests extracted launchers, and exercises packaged preset and diagnostics flows in isolated profiles.

UI and release materials

Layer / File(s)	Summary
GUI regression coverage and repaint handling CS2-VideoConfig-Editor.ps1, build/Invoke-GuiRegression.ps1, tests/Gui-Regression.Tests.ps1	Adds repaint settings for rounded controls and regression coverage for layout, resizing, keyboard navigation, accessibility, contrast, and action state.
Versioned release documentation and metadata README.md, CHANGELOG.md, RELEASE_NOTES.md, RELEASE_CHECKLIST.md, ROADMAP.md, CS2-VideoConfig-Editor.zip.sha256, tests/CS2-VideoConfig-Editor.Tests.ps1	Updates 2.0.0 usage, release procedures, roadmap and notes, checksum metadata, and version assertions.
