Begin splitting the tabs.js monolith: lift the Y3R C4LL domain into a new
call.js module (mirrors permissions.js / schedules.js).
- questionsState + QUESTION_HISTORY_LIMIT move to state.js: they're read by
both the SW4RM container rows (per-agent question-count badges) and the
Y3R C4LL questions domain, so they're cross-domain shared state.
- operator-inbox domain (state + refresh/render/mark/append) → call.js.
- approvals domain (state + sync/apply/render/diff-panel/history) → call.js.
- call.js exposes count getters (activeApprovalCount, operatorInboxCount);
the entry's refreshTabCounts pulls them. Live-mutation paths call an
injected onCountsChanged callback (registered via initCall at boot)
instead of reaching into the coordinator (avoids a circular import).
- renderPeerHives, physically interleaved in the moved range but part of
the SW4RM/peers domain, stays in tabs.js.
Behaviour-preserving; no visual change. Questions domain follows next.
(Recreated after a harness-restart git-object corruption; identical content.)
