docs: correct the multi-agent orchestration documents

[Joob1n]

Summary

The Multi-agent orchestration group from #3522. Four documents were audited; three needed changes.

docs/agent-swarm.md documented a tool that no longer exists. The whole document was built around an agent_swarm tool taking items, a prompt_template and resume_run_ids. #2384 deleted packages/runtime/src/agent-swarm-tools.ts — where AGENT_SWARM_TOOL_NAME = 'agent_swarm' was defined — along with adaptive-swarm.ts, and replaced synchronous fan-out with asynchronous supervision over the Agent Graph. agent_swarm survives only as a tool-result kind on historical records, so a reader following this document would call a tool that is not in the catalog.

Rewritten around what swarm actually is now: an orchestration mode, not a tool. It is entered with /swarm on|off|status|<task> and changes four things — the system prompt, a guaranteed tool set that deliberately omits view_agent_graph, the durable agentSwarmAuthorization field on the Run header, and its own supervisor-wake rule. Items are ordinary child Sessions scheduled as graph work, and agent_swarm_status projects the same graph snapshot, where swarmId is the graphId.

Two questions a reader may reasonably ask, answered here so the diff does not have to carry them:

Was the tool deleted, or renamed and moved? Deleted. The file that defined it declared exactly one tool, the current catalog of 47 tools contains no agent_swarm, no tool anywhere accepts a batch items array, and every surviving mention is the result-kind type — nothing constructs one. agent_swarm_status is a different tool, not a rename: it takes no parameters and only projects a graph snapshot. The capability did move, onto the graph tools.

Is swarm now just a compatibility shell over graph? No. The execution machinery is entirely the graph — one scheduler, one ledger, one control plane. But swarm is a live mode over it, with its own guaranteed tool set, durable authorization record, and supervisor-wake trigger. Only the agent_swarm result kind is pure legacy, kept so old records stay readable.

The Agent Graph chapter had four smaller defects, corrected in both languages so translation_status: synced stays true:

• apps/desktop/src/main/agent-graph-ipc-main.ts does not exist. Graph change events travel through runtime-host-session-domains-ipc-main.ts as agentGraphChanged, and agent-graph-panel.tsx imports its types straight from @maka/runtime-host/client and @maka/runtime-host/protocol.
• apps/desktop/src/main/__tests__/graph-mode-host-contract.test.ts was deleted and has no successor.
• The comparison table described Agent Swarm as "one foreground tool call owns a bounded worker pool" — the removed synchronous model.
• The same table listed Agent Team beside four real mechanisms, but AgentTeam, agent_team and mailbox appear nowhere in the code. The row was removed and the section heading updated to match the rows that remain.

docs/side-conversation.md needs no change. Its unresolved symbols (excludeTurns, moveTabTo, receiveMovedTab, preserveOnClose, onBeforeClose) all sit inside the Codex Reference and Desktop Architecture Snapshot sections, which describe OpenAI Codex and carry their own inspection date.
