docs: dsh 0.1.0-rc.7 / 0.1.1-rc.1: agent teams, authorization flows, expanded pi-ai compat

[github-actions]

This refresh tracks three new dsh npm releases (latest moved 0.1.0-rc.6 → 0.1.0-rc.7, next is now 0.1.1-rc.1) and a large interface expansion in the upstream deepseek-harness docs. Two brand-new services — an Agent Teams domain and an authorization-flow registry — plus a much wider pi-ai wire-compatibility switch surface change what developers can build and how they wire up private OpenAI-compatible gateways. dsh is a developer preview, so this is a breaking-change release: renamed events, a session-projection API redesign, and new config schemas ship without migration paths.

• New npm releases. latest is now 0.1.0-rc.7 (with 0.1.0-rc.8 published 2026-08-19) and next is 0.1.1-rc.1 (2026-08-21) — three versions since the 08-13 snapshot.
• New Agent Teams subsystem (ctx.agentTeams). New @deepseek-ai/dsh-experimental-agent-team and @deepseek-ai/dsh-experimental-tool-agent-team plugins with a new subsystems/agent-team.md page: durable roster, mailbox, and shared task DAG plus ten model tools (spawn teammate, send message, task create/get/update, interrupt, …). Scoped to implicit Team Leads; the dsh-base bundle keeps it disabled behind a profile patch.
• New ctx.authorization service (@deepseek-ai/dsh-authorization). A registry of credential-obtaining flows — registerFlow/begin/cancel/list, one attempt per key, and a new authorization/settled event. The credentials seam is now two key spaces: CredentialRef (env-var-backed) vs CredentialKey (stored grant records with read/modify/delete under lock), and credentials/updated was renamed credentials/reference-updated.
• pi-ai request compatibility, expanded. The user-facing Configure-models guide gains a "Request compatibility" section, and PiAiCompatProfile grew from 2 to ~18 wire-compat switches (supportsDeveloperRole, maxTokensField, supportsStore, supportsStrictMode, supportsEagerToolInputStreaming, cacheControlFormat, …), each pinned to the wire protocols that accept it — for the many OpenAI-compatible gateways that refuse the default OpenAI-shaped requests (e.g. the developer role or max_completion_tokens).
• New file-reference subsystem (ctx.fileReferences). New @deepseek-ai/dsh-file-reference-local plugin with path-only @-mention completion candidates (FileReferenceCandidate) served to host and browser consumers.
• LLM streaming contract changes. BlockAssembler gains interruptedBlocks(), and adapter replay state becomes a structured ReplayEnvelope with per-block entries pruned in step with dropped blocks — replayState's type changed.
• Web server API changes. New webserver/index-inject event and collectIndexInjections()/renderIndex() replace raw index taps as the primary hook; SPA serving tightened (absent/non-file targets are now empty 404s). dsh web also opens the default browser by default (--no-open to suppress), with a new openBrowser config.
• Session projection API redesign. Projections split into host fold states (SessionProjectionStateMap) vs client-visible whole values (SessionProjectionMap) with stateSchema and an optional wire client view — a breaking change for domain plugins that registered projection units.
• Config additions across plugins. permissionMode for claude-code/codex subagents, terminal shellDialect (bash/pwsh) plus a new @deepseek-ai/dsh-tool-pwsh-persistent tool, DeepSeek catalog reasoningEffort: 'low' + maxRequestImageBytes + inputModalities, searchMaxQueries for web tools, and tool-subagent reportDelivery default changed from wakeup to next-step.
• New cookbook page "adding a settings card" — how a plugin registers a settings namespace (Host half) plus a browser card (client half) that pair up on the web settings page.
• Fetcher note: .metadata.json now records "served fallback shell" errors for pricing.md and the R1 news page this run — a fetch failure, not a content change; those files are unchanged. The two new dsh pages were added to llms.txt.
