✨ Highlights

• Native mobile backend. miso can now target iOS/Android by driving the Lynx dual-thread runtime instead of the browser DOM — new Miso.Native module tree, gated behind -fnative. See sample-app-native for a worked example. This is still considered in alpha / beta.
• App-global context. miso's analogue of React Context — one value shared by every Component, seeded via startAppWithContext, read via getContext/view, updated via modifyContext/putContext.
• Miso.Cookie — Cookie Store API bindings (cookieGet, cookieSet, cookieDelete, cookieChangeSub, …).
• canvasSub — drives a <canvas> in a tight requestAnimationFrame loop outside the VDOM diff cycle.
• Miso.Trace — a browser-console Debug.Trace analogue (trace, traceShow, traceWarn*, traceError*, …) for pure code.
• Synchronous Miso.Fetch variants (getJSON_, postJSON_, …) plus cross-thread effects runOnBG / runOnMain for the native runtime.
• Static components — mountStatic / vcomp survive the dual-thread boundary via StaticPtr.
• New cabal flags: -faeson (define Miso.JSON in terms of Data.Aeson) and -ftext (use Data.Text for MisoString on WASM).
• ⚠️ Breaking: View/Attribute gained type parameters, Sub gained a model parameter, Miso.Binding and parent/ROOT were removed in favor of context, Miso.Types.keyed was removed, autocomplete_ now takes MisoString. See the changelog for full migration notes.
• Perf: eager JSVal freeing on WASM (GC pause reduction), StableName dirty-checking extended to context/props, direct main-thread event dispatch.
• Many other fixes below, etc.
