sysadminandClaude Opus 4.8 c3f282ba44 fix: exclude epic and child-only containers from allocator selection (Closes #844)
Epics and parent issues whose body delegates implementation to children are
skipped before ranking with structured reason epic_or_child_only_container.
Title-only "epic" mentions without body/label evidence remain eligible.

"""Allocator epic / child-only container pre-rank exclusion (#844).
Covers:
* Issue #631-shaped child-only epic is excluded before ranking.
* Implementable child issues remain eligible and can be selected.
* Ordinary issues that merely mention "epic" in title/body are not excluded.
* Excluded containers never receive assignments or workflow leases.
* Structured skip reason ``epic_or_child_only_container`` is reported.
