The dsh manifest gains no description field: a bundle's card shows the
package.json description, and the shipped optional bundles carry no
display title or description of their own until localized metadata is
designed. The plugin author tutorial shows the bundle declaration alone.
The dsh installation lists under `dsh.optionalBundles` the bundles it
ships for a person to switch on. The plugin manager reports them as
`optional`, and the Web plugin page shows them first, in a built-in
group with an official tag, off until selected and never removable.
Agent Teams ships this way, so a blank profile offers both of its
layers. Default-product isolation, the workspace constraints, and the
packed-install check accept that one dependency edge and nothing else
experimental.
A bundle's title and one-liner come from `dsh.title` and the new
`dsh.description`, else from the package name and `description`. A
dependency without a bundle patch is no longer listed unless the
profile selects it. The install dialog asks for a package name or
address; a guide under the field shows the three accepted forms with
an example each and ends in a security warning, and the copy no longer
speaks of a plugin ID.
parseCmdline(ctx, program): void only adapts commander control flow to
the launcher: it parses the immutable cmdlineArgs snapshot and turns
help, version, parse errors, and action rejections into a ctx.appExit
request. App validation and the ctx.provide of the app-owned service
live in the program's own synchronous .action(), which commander runs
inside parse — program.error(...) there shares the exit path with a
grammar rejection. Deletes the CmdlinePlan export, its unread ctx
parameter, the type-unsound (() => ({}) as T) default, and the
T | undefined return with its per-caller publish guard.
Adds docs/user/develop/basic/publish.md (+ zh pair, website entry) to the
basics path: the bundle-vs-profile manifest split, dsh plugin add into a
profile, the five-layer loading order, and the GitHub-install build-script
catch — git specs ship sources, so the author owns a self-contained prepare
script and the user owns an allowBuilds allowance that is install-time code
execution; built tarballs and npm need neither.
