perf(tests): move DOM-free jsdom suites to the node environment

Audited the 229 test files declaring @vitest-environment jsdom. 217 need a
real DOM (React rendering, TipTap/ProseMirror, window/document/localStorage,
DOMParser, ProgressEvent) and stay on jsdom; 12 exercise pure logic (yjs
collab-doc conversion, http tool URL building, panel editor store, log
utils, attachment upload, headless TipTap table commands, terminal-session
tooltip helpers) and now run on node, skipping the jsdom boot.

Dropped one redundant test in apply-streamed-markdown.test.ts: the
hand-rolled one-shot peer case is a strict subset of the NON-OVERLAPPING
two-peer test in apply-streamed-markdown.concurrent.test.ts, which also
asserts CRDT convergence and exactly-once survival of the peer edit.
