The `cordis.patch.yml` parser and the comment-preserving writer are the
Loader's format, not a mechanical primitive: they build on the include
plugin's dialect and the Loader's row types, which no other `util` package
does. They now live in `app-boot` as `src/patch-file.ts`, exported as
`@deepseek-ai/dsh-app-boot/patch-file` with its own bundle entry, so the
agent-preset roster and the plugin manager load them without the boot entry.
`dsh-patch-file` goes, with its README and catalog entries; `yaml` moves into
app-boot's dependencies.
A dozen plugin packages already depend on `dsh-app-boot`, so the roster
joining them costs nothing; the note records why the separate package was
tried and folded back.
