Twelve idempotent install scripts matching install-telegram.sh's shape,
one per channel in /new-setup-2's pick list (except Emacs, which uses
a git-merge install flow). Each bundles preflight + fetch + copy +
register + pnpm install + build so a single allowlisted bash call can
replace a chain of permission prompts. Linear's also patches
chat-sdk-bridge.ts for catchAll forwarding; Matrix's runs the
post-install ESM-extension dist patch; WhatsApp-native's covers the
deterministic install portion only — QR/pairing auth still lives in
/add-whatsapp.
Scripts only; new-setup-2/SKILL.md integration deferred pending a
decision on whether to generalize the set-env pattern from 712a0e1
across the Chat SDK channels (each /add-<channel>/SKILL.md's
Credentials section has a similar unapprovable shell chain).
