Resolved 4 override conflicts (AccessibilityPrimitives.h, WindowsTextInputNativeComponent.js, BaseViewConfig.win32.js, BaseViewConfig.windows.js) and removed two orphaned ReactNativeViewAttributes overrides whose upstream base file was deleted.

Adapt RNW native code to upstream changes surfaced by the playground-composition build: - EventEmitter const removal: SharedEventEmitter is now shared_ptr<EventEmitter> (non-const). Drop const from emitter creation in AbiComponentDescriptor/AbiViewComponentDescriptor createFamily (mirrors upstream ConcreteComponentDescriptor) and const_pointer_cast at the EventEmitterForComponent boundary. - ShadowNode::Unshared alias removed upstream: use std::shared_ptr<ShadowNode> directly in AbiPortalShadowNode::layout. - ParagraphComponentDescriptor.cpp deleted upstream (now header-only): remove stale ClCompile entry from Shared.vcxitems. Validated: playground-composition builds, deploys, launches, and loads the RNTester JS bundle. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

…des on Windows Newer RN nightlies include deeply-nested upstream paths that exceed the 260-char MAX_PATH limit, causing 'git checkout' to fail with 'Filename too long' during validate-overrides on Windows CI agents. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
