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.
