The browser app had no tests and no way to run any: package.json shipped dev/build/preview/typecheck, and CI installed Node and pnpm but never ran anything with them. Its densest logic was module-private, so even with a runner none of it was reachable. Extracts four pure modules out of DOM-heavy ones — tree.ts (directory grouping), keys.ts (terminal escape encoding), paths.ts (completion arithmetic), html.ts (one escaper, replacing four copies). Extraction rather than `export` because attach.ts imports xterm's CSS at module level, which a node test cannot load. CatalogStore takes an injectable socket factory, scheduler and refetch, so the reducer and the backoff schedule run without a server. snapshot() now returns a copy: it returned the live object while events mutated it in place, so listeners could not diff and every event rebuilt the whole tree. 36 tests across 6 files, and a `web` CI job running typecheck, test and build. vitest is pinned to 2.x — 4.x requires vite >= 6 and this is vite 5.
