Tianyi Cui 9fddbac095 refactor: unify the Code Mode demos on base-plus-overlay
Both demo:code-mode UIs now share one mechanism: the base example plus a
same-shaped code-mode.cordis.yml include overlay (insert the worker
runtime, flip tools.mode). Previously the REPL side was a hand-forked
example (examples/code-agent) that had also silently diverged — it
dropped compaction and the subagent stack — so the demo's UI argument
switched agents, not just surfaces. The fork is retired: coding-agent
gains the overlay, a Code Mode README section absorbing code-agent's,
and both of its tests (the keyless boot guard, retargeted at the
overlay; the with-key RFC proof, which hand-mounts its own harness and
moves untouched). The RFC's composed-surface and e2e-tier lines, the
examples index, the AGENTS.md smoke table, and the dsh-tools README
link now describe the overlay shape.

Verified live: overlay keyless smoke, with-key code-mode e2e from its
new home, demo:code-mode banner + EOF exit, and the acp handshake.

/**
* Keyless Loader-path smoke for the Code Mode overlay: boot the REAL
* example through the `@deepseek-ai/dsh-stdio-agent` bin against
* `code-mode.cordis.yml` (the cordis Loader, `unwrapExports`, the include
* patches over ./cordis.yml, the worker-thread code runtime, and the
* registry in `mode: code`), then close stdin with no prompt and assert
* the Code Mode banner + a clean exit.
*
* No prompt is ever sent, so the model is NEVER called and no `run_code`
* turn happens — a dummy key lets `llm-deepseek`'s key-PRESENT check boot
* the tree. This is the export-shape guard (postmortem 0001) for the Code
* Mode composition; the with-key proof lives in `code-mode.e2e.ts`.
