Two robustness fixes after a real-world miss where v1.4.7 was uploaded but
the launcher kept reporting v1.4.6 as latest:
1. UpdateChecker: ignore the `latest` field of the manifest entirely.
Always pick the highest SemVer in the versions[] array (filtered by
availableForDownload). Removes a class of "I forgot to bump latest"
bugs at the server.
2. ManifestService: send Cache-Control: no-cache, no-store + Pragma:
no-cache when fetching. The user explicitly clicked "Check for
updates", they want fresh data — bypass any intermediate cache
(browser-style HTTP cache, OVH static handler default 2-day expires).
3. sign-manifest.php: after hashing the uploaded ZIPs, auto-update
`manifest.latest` to the highest version that actually has a ZIP
on the server. Prevents the same drift the client now ignores, but
keeps the field meaningful for any consumer that reads it.

Client (C# / .NET 8 / WPF, MVVM via CommunityToolkit.Mvvm):
- PSLauncher.App: WPF UI dark theme (Epic-style sidebar + hero + big play button)
with UpdateAvailableDialog rendering Markdown release notes via Markdig.Wpf.
- PSLauncher.Core: services for installation registry (scans Proserve v{X.Y.Z}/),
process launcher, manifest fetch, SHA-256 integrity, HTTP download with
progress, ZIP install via .tmp + atomic rename, update orchestrator.
- PSLauncher.Models: RemoteManifest, InstalledVersion, LocalConfig DTOs.
Server (PHP 8 for OVH mutualisé, deployed under www/PS_Launcher/):
- Front controller + routes /manifest and /releasenotes/{version}.
- Static signed-manifest workflow with tools/sign-manifest.php CLI to
recompute SHA-256 and sizeBytes after each ZIP upload.
- .htaccess: HTTPS redirect, rewrite, security headers.
- config.example.php template; real config.php is gitignored.
Cohabiting versions: each release lives in its own Proserve v{version}/ folder
under installRoot. Old versions are never deleted automatically.
Roadmap: v0.3 = HTTP Range resume + Polly retry + state.json,
v0.4 = MySQL license + Ed25519 signatures + DPAPI, v0.5 = settings/UX polish.
