Subject: [PATCH 02/13] Bump frontend and backend for review fixes on
 chat-process-split-r1

Why: the review of feature/chat-process-split-r1 required untracking the
frontend node_modules symlink, per-turn interleaving of live parts with
tool-call-driven process marking, a long-reply excerpt, and marking
artifact_ref parts as process in the backend.

Evidence: frontend 22a8723 (untrack symlink) + 754ce83 (interleave and
mark); backend ae8e5d0 (artifact process). make test green: frontend
27/27, ui 35/35, backend go test ./... ok.

Impact: parent task branch now points at the reviewed submodule commits;
ready for PR.

Subject: [PATCH 04/13] Record review-fix evidence on the chat-process-split-r1
 task card

Why: the card and PR description are one document; the 2026-09-30 review
fixes (symlink untrack, per-turn live interleaving, artifact process mark)
need to appear on it.

Evidence: card lists frontend 22a8723/754ce83, backend ae8e5d0, Dev
596d02c with the verification outputs (vitest 27/27, go test ./... ok,
make test exit 0).

Impact: .task documentation only.

Subject: [PATCH 05/13] Bump gitlinks to submodule main-merge commits

Why: task-sync requires a clean tree; both submodule branches now carry
merges of their respective mains (backend 9e694c0, frontend 765789f).

Evidence: git submodule status shows the new SHAs; backend go test ./...
ok after its merge; frontend vitest 32/32 after its merge.

Impact: gitlink update only.
