This PR contains the work done to rename the _Web_ package as _Infrastructure_, to provide a clear naming and purpose to this particular package within the project. To provide further details about the work: * Infrastructure * Asset fingerprinting: an FNV-1a token derived from the static files directory, appended as ?v= to asset URLs so deploys bust caches; pre-rendered pages also revalidate via weak ETags. * New middlewares: fixed-window RateLimitMiddleware (per-client budgets keyed by trusted X-Forwarded-For or remote address) and VaryMiddleware (Accept-Encoding on every response); SecurityHeadersMiddleware now also stamps error responses. * Auto-generated HEAD endpoints, cache max-age configuration, and Docker build/Compose refinements. * Protocols and scaffolding: Asset/AssetExtension, the Page protocol (viewport, stylesheets, scripts, versioned URLs), and LocalizedRequestContext. * Rate limiter's counter store swapped from an actor to a Mutex (no executor hop per request) with amortized batch eviction instead of O(n²) scans under client floods. * FingerprintAssets reports unreadable files to a logger instead of silently producing a token that never busts their cache.
