feat(standalone): sexprDiff structural comparator + vitest (0003/0004 §B)

Add the shared, uuid-keyed structural s-expr comparator (README §B) used by both the live drift check (0003) and the round-trip tests (0004), plus a vitest setup. - wasm/collab/sexpr-diff.ts: zero-dependency module (importable from standalone app code and the Playwright specs). Tokenizes s-expr text into nested lists, indexes item nodes by their direct (uuid "X") child, compares item sets order- insensitively as multisets of normalized children, emitting { equal, added, removed, changed } with per-property a/b. ignoreTokens drops volatile tokens. False-positive-free only for same-serializer inputs. - wasm/collab/sexpr-diff.test.ts: 15 cases (parse, equality, changes, ignoreTokens). - vitest config + test scripts (node env, isolated from the app build).
