New steering job-config-layering.md: queue = scheduling policy, application
profile = what the application needs and how it runs (resreq, task range,
execution settings, pre/post-exec, limits), project = resource ownership.
Only two interactions: the job overrides a profile attribute marked
default (fixed: not at all; select: only ANDed terms), and queue ceilings
or project quotas check effective values (reject if never satisfiable,
pend if full now). Replaces the simplified job > app > queue rules.
Queue pre_exec/post_exec are deprecated with queue res_req: the profile's
pre/post-exec fills the worker's existing outer layer, the job's own stays
the inner layer, allowed or forbidden by the profile.
job-config-merge and application-profile briefs and the roadmap follow;
CLAUDE.md lists the new steering file.
