Merge origin/master (generic task runtime #219, single-exe closure, package renames)

Browse Source 
Semantic resolutions beyond line merges:
- The bash seam keeps resolveMode + the bash/resolve-mode waterfall on
  master's task-free BashExecutor (run/start/resolve only; BashProcess
  handles); tool-bash consults it at its stamping site and escalation
  baseline on master's render/background split, with a waterfall test on
  the recording executor.
- dsh-mode's BASH_FAMILY narrows to ['bash']: bash_output/bash_kill are
  replaced by the kind-generic task_output/task_kill, which span every
  task kind and only observe or stop work, so the access cap withholds
  only the starter it can reason about.
- The plan-mode snapshot suite adopts master's pin grammar (tool-schema
  sidecars; the expectedHeaderSnapshots extension is gone — the exit
  transition deltas, and entering-before-turn-1 needs no second
  snapshot); modes-advertise joins the plan header class (no-model, so
  membership is vacuous). Fixtures re-recorded on the acp-demo bin;
  the replay overlay gains the passthrough sandbox runner.
- examples/plan-acp-agent rewires to @deepseek-ai/dsh-acp-demo and drops
  its tool-bash entry (the spine bundle now composes it); dsh-stdio (the
  renamed stdio-chat home) keeps its /mode command and gains the dsh-mode
  peer edge; the acp bridge keeps the modes surface beside master's
  permission presets.
- mode README gains the Model Experience / Known Limitations sections the
  new README gates require; AGENTS.md ceiling 1370 → 1440 for the kept
  mode/ layout line and Agent efficiency section.

# Examples
Runnable demos (not workspaces) that showcase how the harness is wired. Each example is now a **thin leaf**: a `cordis.yml` that picks the swappable backends (an LLM adapter, a bash executor), loads ONE app package, and may add optional product tools or demo-only mocks. The composition — the spine, the front-door cluster, and the boot glue — lives in the app packages ([`@deepseek-ai/dsh-stdio-agent`](../packages/ui/stdio-agent), [`@deepseek-ai/dsh-acp-agent`](../packages/ui/acp-agent)) and the [`@deepseek-ai/dsh-agent-core`](../packages/core/agent-core) bundle they share. There is no `start.ts`; the `demo:*` scripts invoke each app package's `bin`.

## coding-agent
A REPL agent demo: DeepSeek V4 + the `read`/`write`/`edit` filesystem tools + the bash tool suite, `subagent` delegation, and the `todo_write` task tracker on the same `@deepseek-ai/dsh-stdio-agent` app. The UI is a terminal readline REPL.

Run with: `pnpm run demo:repl` (needs `DEEPSEEK_API_KEY` in the environment or a gitignored repo-root `.env`). See [coding-agent/README.md](coding-agent/README.md) for details.
Its `code-mode.cordis.yml` overlay flips the same tree to **Code Mode**: the worker-thread code runtime is loaded and the tool registry runs `mode: code`, so its registry contribution is the reserved `run_code` transport plus a generated TypeScript SDK section, and the model composes the other tools by writing a program whose output it curates. Run with: `pnpm run demo:code-mode` (the REPL is the default UI; `acp` as the argument serves the acp-agent example's same-shaped overlay instead) — see the [Code Mode section](coding-agent/README.md#code-mode) for what to try.
Run the Code Mode overlay with `pnpm run demo:code-mode`, or pass `acp` for the ACP example. See the [Code Mode example](coding-agent/README.md#code-mode) for its composition and a sample task.

## acp-agent
An agent demo exposed as an **Agent Client Protocol (ACP)** server over JSON-RPC stdio, via the [`@deepseek-ai/dsh-acp-agent`](../packages/ui/acp-agent) app — drive it from Zed or any other ACP client. Also the home of the keyless snapshot tests.
An agent demo exposed as an **Agent Client Protocol (ACP)** server over JSON-RPC stdio, via the [`@deepseek-ai/dsh-acp-demo`](../packages/examples/acp-demo) app — drive it from Zed or any other ACP client. Also the home of the keyless snapshot tests.
Run with: `pnpm run demo:acp` (needs `DEEPSEEK_API_KEY`); `pnpm run demo:code-mode acp` boots the same server in Code Mode via the `code-mode.cordis.yml` overlay. See [acp-agent/README.md](acp-agent/README.md) for the Zed setup and the snapshot-test design.
The default `cordis.yml` composes [`@deepseek-ai/dsh-sandbox-local`](../packages/sandbox/sandbox-local), [`@deepseek-ai/dsh-bash-sandbox`](../packages/bash/bash-sandbox), [`@deepseek-ai/dsh-user-approval`](../packages/ui/user-approval), and [`@deepseek-ai/dsh-permission`](../packages/ui/permission). A capable client gets one `Permissions` select: `workspace-write` confines bash to the configured workspace and asks before a wider retry, while `danger-full-access` removes file confinement and disables approval prompts. A denied command can therefore surface a one-shot `session/request_permission` prompt in the editor; "Allow once" runs exactly that retry under the requested wider mode.
## plan-acp-agent
The ACP server with **session modes** composed ([`@deepseek-ai/dsh-mode`](../packages/mode/mode)) — the editor's mode picker switches the session into plan mode, the model works under the read-only allowlist, and it leaves through the user-reviewed `exit_plan_mode` tool (the review arrives as an elicitation form).
The ACP server with **session modes** composed ([`@deepseek-ai/dsh-mode`](../packages/mode/mode)) — the editor's mode picker switches the session into plan mode, the model works under the plan guidance section with bash clamped to a read-only sandbox by plan mode's `access` cap, and it leaves through the user-reviewed `exit_plan_mode` tool (the review arrives as an elicitation form).
Run with: `pnpm run demo:plan-acp` (needs `DEEPSEEK_API_KEY`). See [plan-acp-agent/README.md](plan-acp-agent/README.md).
## sandbox-acp-agent
The coding agent with its bash executor swapped for the sandbox stack ([`@deepseek-ai/dsh-sandbox-local`](../packages/sandbox/sandbox-local) + [`@deepseek-ai/dsh-bash-sandbox`](../packages/bash/bash-sandbox) — the one-entry executor swap the `ctx.bash` capability seam exists for), served over ACP with [`@deepseek-ai/dsh-user-approval`](../packages/ui/user-approval) mounted — the first composition where the approval loop is LIVE: a sandbox denial escalated by the model becomes a `session/request_permission` prompt in the editor, and "Allow once" runs exactly that command under the wider mode.
Run with: `pnpm run demo:sandbox-acp` (needs `DEEPSEEK_API_KEY`; bwrap, a Landlock-enforcing kernel, or macOS for confined runs). See [sandbox-acp-agent/README.md](sandbox-acp-agent/README.md).
