Summary

• Workflows (/workflows) no longer lists Myra's own deploy source or any hand-authored agent — routines-api.ts now filters deployments whose backing workflow-kind asset name is MYRA_SOURCE_CONFIG.assetName or matches agent-<slug>-source (the exact naming agent-deploy.ts already owns, exported as isAgentDeploySourceAssetName). Both markers are asset-naming, not runtime state, so the list stays accurate without a live-run lookup.
• Agents (/agents) is now a plain roster: display name, Live/Starting status, and a "Chat" action that opens /chats/<assetId> via the existing chat path helpers. It reads through listChatAgents (chat/threads-api.ts) — the same source the chat picker already uses — instead of the old workflow-definitions/instances model.
• Create-agent stays in the sidebar's "+" menu; the roster picks up a newly created agent through the same chatKeys.agents query key, invalidated by useDeployAgentMutation.
• Command palette's agent results now open a chat instead of the deleted agent-detail route.

Deleted

• apps/web/src/pages/agent-detail-page.tsx and its route (AGENT_DETAIL_PATH) — health/events/approvals detail view had no remaining use once the roster stopped linking to it.
• apps/web/src/agents-directory.ts — the workbench-host-filtering/display-name binding it provided was only consumed by the roster and detail pages just removed.
• agentIdFromPath (path-ids.ts) and its test — no longer referenced once the detail route is gone.
• Dead exports trimmed from agents-api.ts (useAgentDirectory, loadAgentDirectory, run health/events/approvals hooks, listAgentInstances, getAgentRun, listCatalogModels) — all were only used by the deleted pages.
• The Agents-specific case in run-status-tone-parity.test.ts (AGENT_ROSTER_STATUS_TONE) — the roster's status vocabulary (Live/Starting, reachability) no longer overlaps with RunStatus, so the parity guard no longer applies.

Test plan

• bunx tsc -p apps/web --noEmit
• bun run fmt
• bun run lint
• cd apps/web && bun run build
• bun test ./src (from apps/web) — 584 pass
