docs(e2b): re-home the overlay section on master's README

Browse Source 
Master rewrote the headless README around the profile CLI and removed
cli-demo; the replay had resurrected the old body. The branch's claim is
the E2B overlay section alone, now inserted into master's text with the
credential-gated live composition e2e as the runnable instruction (the
config-file demo runner no longer exists).

Headless one-shot agent wiring: DeepSeek V4 + local bash and filesystem tools + subagent delegation + workflows and fresh-agent Ralph iteration + `todo_write` + JSONL persistence, with [`@deepseek-ai/dsh-cli-demo`](../../packages/examples/cli-demo) as the app front door.
This directory owns the replay and real-model test composition for a headless coding agent: DeepSeek V4 + local bash and filesystem tools + subagent delegation + workflows and fresh-agent Ralph iteration + `todo_write` + JSONL persistence. It explicitly mounts the shared agent spine, one root agent, persistence, and checkpoint policy; it is not a second product front door.

Exactly one nonblank positional task is required; quote tasks containing spaces. There is no `-p` flag. `text` prints the last text-bearing assistant message, `json` prints one DSH-native result record, and `stream-json` emits the top-level session's canonical task-turn events before that record. Child sessions surface only through parent tool events and results.
The product command is [`dsh run`](../../apps/cli/README.md): it accepts one nonblank task, creates and persists a fresh session, prints the final assistant text, and exits. The root `demo:headless` script is only an alias of that command.
Each invocation creates and persists a fresh session, runs all model and tool steps in one turn, flushes, disposes, and exits. This is non-interactive automation: there is no prompt, approval, resume, second turn, or stdin context. The configured tools can mutate the launch workspace, run commands, spawn child agents, and consume provider tokens.
Snapshot suites run this directory's configuration through [`tests/fixtures/headless-driver.ts`](tests/fixtures/headless-driver.ts), an unexported test-only process that emits canonical session events as JSONL before its result record. That stream is test infrastructure, not a supported CLI output format. Child sessions surface only through parent tool events and results.
## E2B POC overlay
[`e2b.cordis.yml`](e2b.cordis.yml) replaces the local filesystem and subprocess providers with one shared E2B sandbox while retaining `dsh-bash-local` and the same model-facing tools. Put `E2B_API_KEY` beside `DEEPSEEK_API_KEY` in the gitignored root `.env`, then run:

Put `E2B_API_KEY` beside `DEEPSEEK_API_KEY` in the gitignored root `.env`, then run the credential-gated live composition, which drives FS, Bash, PTY, and LSP in one sandbox and proves final deletion:
```sh
pnpm run demo:e2b "create hello.txt, read it back, and run pwd"
pnpm exec vitest run --config vitest.e2e.config.ts packages/e2b/e2b/tests/composition.e2e.ts
```
The overlay creates the same absolute cwd inside the sandbox, but it does not upload or mount the host workspace. File and Bash mutations exist only in E2B; Cordis, model calls, agent/session state, session logs, skills, and SDK buffers remain on the host. The demo kills its sandbox on timeout and disposal. It is a provider-composition POC, not a whole-harness migration or a workspace-sync feature.

## Advanced and snapshot wiring
## Advanced configuration
[`advanced.cordis.yml`](advanced.cordis.yml) adds Code Mode and the Cordis tools to the shipped leaf. [`advanced.cordis.snapshot.yml`](advanced.cordis.snapshot.yml) replaces only the live LLM with replay. The tests under [`tests/`](tests/) own the keyless real-Loader smoke, key-gated world-verified smoke, and the `stream-json` replay snapshot with its parent and child session fixtures.
The package-level [CLI contract](../../packages/examples/cli-demo/README.md) documents output records, exit status, cancellation, persistence, and model/token effects.
