imccyu 6f77da4c8c refactor: relocate demo app bundles to packages/examples/*-demo
Move the agent-spine bundle and the stdio/ACP/JSON-RPC app packages out of
core/ and ui/ into a new packages/examples/ group, renamed with a -demo
suffix so the npm name marks them as non-product surface:

  core/agent-core   -> examples/agent-spine-demo  (dsh-agent-spine-demo)
  ui/stdio-agent    -> examples/stdio-demo        (dsh-stdio-demo)
  ui/acp-agent      -> examples/acp-demo          (dsh-acp-demo)
  ui/jsonrpc-agent  -> examples/jsonrpc-demo      (dsh-jsonrpc-demo)

Update every code/config/test reference and reference-only doc mentions, and
regenerate module-graph, config-catalog, and doc-graphs. The jsonrpc bin
(dsh-jsonrpc-agent) and single-file exe (dsh-jsonrpc-agent-pkg) keep their
names; the SDK runtime-startup surface is reconciled separately.

# RFC: Trim unreachable ACP bridge surface — the branding knobs and the kind-sniffing fallback
Status: implemented
## Problem
Two pieces of `dsh-acp` surface were unreachable from any shipped configuration:
1. **`AcpConfig.agentName` / `agentVersion`** (`packages/ui/acp/src/index.ts`). The shipped app package hands the bridge only `{ model }` (`packages/examples/acp-demo/src/index.ts`), so no leaf `cordis.yml` — the only production config surface — could set the knobs at all; they were settable solely by direct-mounting the bridge, which only a unit test did. Every snapshot golden — the hook-matrix scenarios included — pins the schema defaults (`deepseek-harness-acp` / `0.0.1`). The pair also carried a live `TODO(double-default)`: the literals existed twice (schema `.default(...)` plus `??` fallbacks), with the TODO asking to pick one home.
2. **The `toolKindFor` name heuristic** (same file) special-cased `bash*`/`read*`/`write`/`edit*` tool names in the generic-fallback path. Since the [render-intent union](../architecture/2026-07-02-tool-render-intent-union.md), every first-party tool those arms matched ships its own `presentCall` carrying its kind, and the presenter-less production tools (`subagent`, `subagent_fork`) fell through to `other` anyway. The arms were production-reachable only when a tool declined to present its own call — a `presentCall` that THROWS (the containment fallback), or model arguments that fail the tool's schema so `defineTool`'s `presentCall` wrapper returns `undefined` (e.g. a `bash` call missing the required `description`) — and the bridge's own module doc states the design rule the heuristic violated: "the bridge never special-cases tool names".
## Decision
Hardcode the existing handshake identity `{ name: 'deepseek-harness-acp', version: '0.0.1' }` at initialization and remove the unreachable config fields and duplicate defaults. Replace `toolKindFor` with neutral `'other'` at both presenter fallbacks. Normal first-party presentations are unchanged; malformed or failed presentations now render an honest generic card instead of inferring a kind from the tool name. Initialize tests and snapshots pin the handshake; only the malformed calls in `hook-codex-posttool-block` change fallback card kind.
## Alternatives considered
### Why not keep them?
Branding can return when the app package exposes it to deployments. Inferring presentation from unknown tool names violates the render-intent contract; neutral fallback cards also preserve raw input for malformed calls and broken presenters.
## Consequences
Nothing beyond the fallback rendering trade described above — degenerate paths whose neutral card is more diagnosable than an inferred first-party one.
