`collectCliHelp` stops propagating an alias when it reaches a page
already on the current path, so a `help [command]` row that prints its
parent's help no longer recurses until the stack overflows. `serve|s`
command rows are split into separately collected names.
The CLI reference and upgrade guide describe the forwarded-argument
boundary that Commander applies, including a leading pnpm option, and
args.spec.ts pins that `--profile` placed after a leading pnpm option is
forwarded. Generated pages use the repository's two-line generated
header, and docs/AGENTS.md lists the CLI help among the generated
references.

`scripts/gen-cli-help.ts` runs the source `dsh` launcher with temporary
Harness and Agents homes and captures the launcher, `dsh plugin`, and every
shipped profile's text help (profile names come from `PROFILE_TEMPLATES`).
It recursively discovers subcommands from each page's `Commands:` section,
shows identical alias help once with every invocation, and writes
`docs/cli-help.md`, its Chinese page, and their pairing record. The record
resolves links between the two pages as written, so a first run already
matches `verify-translation-pairing`. `verify-cli-help` checks all three
files and runs as the `cli-help` doc-sync leaf, which the static CI lane
also runs on an unbuilt tree.
`dsh plugin` now owns `-h`/`--help` and reads its own options only before
the forwarded pnpm arguments: `dsh plugin --help` prints its help instead of
failing on the missing `--profile`, while everything after the pnpm command
(including `-h`, `--help`, and `--profile`) reaches pnpm verbatim. A
`--profile` placed after the pnpm command is no longer accepted; the
v0.2.1-alpha.1 upgrade guide covers the migration.
