Add the Manifest V3 extension runtime to lynxx-wallet-sdk backing window.lynxx for concurrent dApps: - ProviderQueue: thread-safe FIFO queue that keeps exactly one signing modal active at a time; popup dismissal rejects the active request with USER_REJECTED and immediately advances to the next in line; dispose() settles every in-flight task so long-lived workers leak nothing. - LynxxBackground: service worker that validates sender.origin / sender.frameId on every IPC message, rejects untrusted iframes and opaque origins with ORIGIN_MISMATCH, and keys queue/popup state by internal ids so identical client ids from different tabs never collide. - OriginPolicy: strict CORS-style sender verification (top-frame only, optional origin allowlist, extension-id + extension-URL check for popup messages) that still accepts windowed popups. - Provider bridge + content script: window.lynxx with postMessage request/ response correlation and a top-frame-only content script. - Docs: README section and CHANGELOG entry. - Tests: 39 unit tests covering FIFO ordering, single-active-modal guarantee, popup-close queue advance, iframe rejection, cross-tab id isolation, dispose cleanup, and a 1,000-request leak check.
