feat(content-server): scaffold SVSim.ContentServer
New ASP.NET Core 8 web project, standalone (no project references). Serves the CDN-mirror tree from a configured root via UseStaticFiles mounted at /dl/, with ServeUnknownFileTypes=true + DefaultContentType=octet-stream since blob filenames are bare MD5 hashes with no extension and asset extensions (.unity3d/.acb/.usm) aren't in the default MIME map. Configuration: SVSIM_CONTENT_ROOT env var (or Content:Root in appsettings, or --Content:Root cli arg) points at the asset root containing the dl/ subdirectory. The asset root is populated by data_dumps/scripts/ content_cdn_mirror.py in the outer repo (~22 GB Eng+Jpn). Listens on port 5149 (distinct from EmulatedEntrypoint's 5148). Lightweight request logging via inline middleware emits status/method/path/ms for every request. /health returns "ok". End-to-end smoke verified against the populated working copy at 4670rPsPMVlRTd2: - Both lang tier-1s served (Eng 1013b / Jpn 955b), MD5s match live CDN. - A category manifest (bg_assetmanifest Eng) served + verified. - A 4.5 MB font asset bundle served + MD5-verified. - A Jpn voice from Sound/Jpn/ served + MD5-verified. - Hardlinked content (master_ai_ally_common.unity3d, hash shared across langs) served identically from both Resource/Eng/ and Resource/Jpn/. - 404 for missing blobs (correct).
