docs(dev-guide): package.install needs dockerImage too; helper gotchas

Browse Source 
Learned installing alby-hub/phoenixd for real: the id-only payload fails
with 'Missing dockerImage' (the store normally injects the image from the
catalog), the session helper silently reuses a stale cached session
without ARCHY_FORCE_LOGIN=1, needs jq, and its set -euo pipefail kills an
interactive shell chain without output — so the guide now wraps the flow
in a heredoc subshell.

Three things to know before using it: it needs `jq`; it reuses a cached
session from `/tmp/archy-rpc-session-<uid>` unless `ARCHY_FORCE_LOGIN=1` is
set (a stale cache fails every call quietly); and it sets `set -euo pipefail`,
so run it inside a script or subshell — sourcing it into your interactive
shell makes the first failed step kill the whole chain without printing
anything.
