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: Make the shared example base providerless

Status: rejected — superseded by Extract example apps into packages, which moves the spine into a dsh-agent-spine-demo bundle and deletes the base*.yml files, so there is no shared base YAML left to rename.

Problem

The examples had two shared base files: examples/base-core.yml was providerless, while examples/base.yml included that core plus the real llm-deepseek adapter. Snapshot replay needs the providerless core with llm-replay, because loading the real adapter without a key throws. The normal demos need the real adapter. The result was a naming inversion: the file named base.yml was not the reusable base for all examples, while the true base was base-core.yml.

The split was understandable, but it made every config explanation longer. It also led to awkward test setup like a keyless smoke test carrying a dummy API key so an adapter could boot even though the model is not called.

Proposal

Rename the providerless core to examples/base.yml and make adapter selection explicit in each concrete example. The coding and ACP real configs add a tiny llm-deepseek include or local block; snapshot config adds llm-replay. Delete examples/base-core.yml.

The shared base should contain only provider-neutral services and tools: llm, sessions, system prompt, tools, agents, invariants, bash executor, and bash tool schemas. Anything that chooses a model provider belongs at the leaf config.

Acceptance criteria

  • examples/base.yml is providerless.
  • examples/base-core.yml is deleted.
  • Real demo configs explicitly add the DeepSeek adapter.
  • Snapshot replay config includes the same providerless base and its replay adapter.
  • The examples README, example-specific READMEs, and RFC references stop explaining "base = base-core plus adapter".

What we give up

Real demos lose one layer of convenience: each must opt into the adapter. That is the right default for examples, because adapter choice is the variable part and providerless wiring is the shared product core.
