v0.10.0 - complete standard ACP surface + session watch

What's new

Standard ACP surface completed

Method	Behavior
session/list	every persisted + live session (id, cwd, title)
session/resume	reopen a persisted session without replay (standard form of the vendor method)
session/load	reopen and replay the transcript as user_message_chunk / agent_message_chunk frames
session/set_mode	default ⇄ plan, bridged to dsh plan mode, with current_mode_update push
available_commands_update	the dsh command registry, advertised per session; a single /command prompt routes through it
image prompt blocks	validated media types, persisted via the dsh attachments service (promptCapabilities.image)

dsh/sessions/watch

Any connection can now subscribe to any session's translated live stream - dsh/session/update frames in the same shapes the owner receives. Dashboards, orchestrators, and audit tooling can observe a conversation they did not start. Agent-status transitions also push dsh/changed {agents} (throttled) for live tree tracking.

Scope note: the dsh↔dsh client half, discovery, and identity move to a separate package (roadmap) so this server stays single-purpose.

v0.9.0 - host plane over ACP

What's new

Host plane over ACP — dsh/* vendor extensions

ACP v1 standardizes one conversation, not the host around it. This release exposes the host through read-only vendor methods any client can consume:

Method	Returns
dsh/sessions/list	every persisted + live session (id, title, createdAt, cwd, parentSession, acp flag)
dsh/sessions/read	one session's transcript as {seq, type, text} entries
dsh/sessions/resume	reopen a persisted session as a live ACP session (full context)
dsh/jobs/list	background jobs (id, kind, label, status, owner)
dsh/goals/list	active goal per live agent (objective, phase, rounds)
dsh/skills/list	installed skills (name, description, provider)
dsh/agents/tree	live agents with parent/model/cwd (the subagent tree)

Push: dsh/changed {topics} notifications fire on turn ends, session lifecycle, and job changes.

Interop-safe by construction — vendor traffic is sent only to connections that opted in via the schema-sanctioned clientCapabilities._meta['dsh/extensions'] extension point. Standard clients (Zed, acpx, Neovim plugins, …) see a fully standard ACP server. Each method degrades to a clean -32601 in compositions without the underlying service.

Built-in web UI: host sidebar

The serve-mode web client (GET /) gains a host sidebar next to the chat: sessions with titles and one-click resume + transcript loading, jobs, goals, skills, and the live agent tree — auto-refreshing on dsh/changed.
