housekeep-backlog — Living register of parked work

Degree of freedom: MIXED. Discovery scan [LOW freedom — run exactly]. Classification, dedup, priority [HIGH freedom].

Apply-now for the register only. You do not implement backlog items here. Every plan-* skill creates parked work; this is the collector. The failure mode is not making the inventory — it goes stale within a month and nobody can tell if debt is shrinking. So this is docs-adr for parked work: regenerate, diff against the last run, keep stable IDs.

Prefer docs/BACKLOG.md. Use a root BACKLOG.md only if the host already has one.
