Umbrella analyses: lc cannot run at a parent that composes path-backed sub-analyses

[lhparker1]

A parent astra.yaml whose outputs are all from: aliases into analyses.<id>.path: sub-analyses (e.g. lightcone-vrecon-leakage) can be lc init'd, but lc status there fails:

Error: output id 'replication.catalog_ph002' contains a dot, so the manifest beside it could not be told from the output's own name.

The resolver inlines path-backed children under dotted ids, and assets.output_path then tries to place them under the parent's own results/. lc has no notion of an output living in a child project's results folder, so an umbrella is currently view-only: you write its universe by hand and run lc inside each part.

Wanted

• lc status / lc materialize at the parent resolve a path-backed child's outputs to <path>/results/<child universe>/… and delegate runs to the child.
• A clear error when a path-backed child is not configured in the parent's universe (today the TS SDK silently binds nothing, and viewers show every output as unmaterialized).
• Related, astra-tools: astra universe generate at a parent should emit analyses.<id>.universe: <child's default> for path-backed children instead of omitting them, since that is the only shape that resolves.

Nothing in lc init should edit the parent's universe file from a child; the reference belongs where analyses.<id>.path: is added.
