Integrate the Commander argument adapter and dsh-front-door work with master's
config-tree `dsh web` (#601: AppCLIEntry + apps/cli/cordis.yml) and the
packages/ui/acp → packages/acp/acp relocation.
- web.ts: keep master's AppCLIEntry-based boot, but take the adapter's parsed
(host, port, dev) instead of an internal parseArgs. The adapter's host/port
defaults (127.0.0.1/3080) match cordis.yml, so always passing them is
behavior-equivalent to master's "undefined keeps the yml default".
- apps/cli/package.json: master's expanded config-tree dep set + commander.
- retire-readline Agent Note: point the TUI refusal proof at
apps/cli/tests/built-bin.e2e.ts (both languages), re-record the pair.
- READMEs reconciled (demo-bin removal + master's ACP/channel rewording).
