Mount every external bundle layer as a cordis:contained-group entry
`bundle/<package>` whose rows carry a `<package>/<id>` prefix, so one
community bundle that no longer loads records a failure in the root
`pluginFailures` registry instead of rejecting the whole Loader
transaction, and two bundles may declare the same row id. Classify
layers by origin (`builtin` for the template bundle and
`dsh.profile.firstParty`, `external` for profile dependencies) and let
`dsh.bundle.stage: boot` or `dsh.profile.stages` opt a bundle out of
isolation when it provides a service built-in rows inject; a built-in
row left pending beside an isolated bundle still fails boot and names
the bundle.
Keep `installFailLoud` for the boot transaction only and install
runtime guards afterwards: an unhandled rejection is reported and
contained, an uncaught exception is reported and exits. Report nested
fiber failures under built-in entries as advisory lines.
Provide `ctx.profileRuntime` from the launcher (layers with trust and
stage, row origin, user-disabled rows, recomposition through the root
include) and probe installed packages in a child process
(`probePackage`, cached under `profiles/<name>/.dsh-plugins/`). Split
installation from enablement in `reconcileInstalledBundles`; the CLI
keeps install-means-enable. The plugin inventory now reports `trust`,
`package`, `disabledBy`, and `failure` per row and lists rows only the
failure registry knows.
