Merge branch 'stack/agent-profiles-3-wire' into stack/agent-profiles-5-web-ui

The Client API carrier's `agentPresets` member was the one member of its class without an `IApiClient[...]` annotation. Inferring it inlined `AgentPresetEntry` into the emitted declaration by the specifier TS picks — the host `index.ts` — dragging the whole gateway, and with it the host `Context` merges, into every Client program importing the carrier. Annotated like its siblings. `ApiRemoteAgentOptions.setup` now takes the inspected session rather than its header alone: this layer resolves a resumed session's preset from the LOG, because a session that switched while blank ran its turns under the newer composition and the header is written once at creation. Conflicts: apps/web/tests/snapshots/*/*.expected.md packages/client/ui-conversation/src/client/skeleton/InputBar.tsx packages/host/apiproxy/src/api-proxy.ts scripts/doc-budgets.manifest.json
