Address the ds-review-bot findings on 9aea4b0804:
- Drop the stale "freshly created" wording from the resolveAgent `@returns`
and rewrite its leading comment for the two remaining identity paths.
- Rewrite the README run-flow paragraph (EN and ZH), the intro sentence, and
the cordis.patch.yml header comment for adopt-only.
- Add a real-composition two-wake e2e: capture the generated id from the first
`--json` wake, resume it by `--session-id`, and assert one persisted log holds
both tasks. `runLoaderSmoke` gains an optional caller-owned `cwd` so both
wakes share one world; the harness leaves that directory in place.
