Seven tool containers move to bundles the node's runtime serves, given their words (hq ADR 0192)

baserow, confluence, gitlab, jira, letta, searxng and unifi: each runtime container's
environment becomes its tools bundle's env, mount targets folded back into the host paths they
came from; baserow and letta reach their service on the published port rather than a container
network name. The container, base images, Dockerfile and the module's own bus credential go,
and the state directory where only that credential lived. Tool code is unchanged: every client
is built from the environment the contributor is handed.
