Bring NucleicRemote closer to desktop parity in two areas (the core
sync loop was already at parity — shared protocol, control scope).
Transcript fidelity (iOS): a client-side TranscriptProjection coalesces
streaming text by messageID and folds each tool call's lifecycle
(start/deltas/complete/result/fileChange) into one expandable card —
fixing the duplicate started+completed rows. Adds Markdown bubbles, the
gold Orchestra card for Task/Agent spawns, and the previously-dropped
usage/cost, rate-limit, file-change, turn-boundary and session-started
rows, plus a context-window % header badge.
Mid-session controls + model catalog (protocol/host/iOS): project the
host ModelCatalog over the wire as WireModelCatalog (in Welcome); add 5
control-scope setters (setSessionModel/Effort/Auto/AutoShip/ShipBranch)
backed by the existing AppStore.mutateSession + SessionController hooks;
enrich WireSessionSummary with model/effort/auto/autoShip/shipBranch/
contextInputTokens (all forward-compatible). The composer gains a model
picker and a catalog-driven effort menu (per-backend caps: Codex→xhigh,
Grok→auto), and the session header gains a model/effort/auto/autoship
control bar.
Tests: CBOR round-trips for the new messages, Welcome.modelCatalog, the
new summary fields, forward-compat decode of old bytes, and the setters
reaching the host. Verified in the Simulator (NUCLEIC_DEMO=1).
