Software Factory Run Audit

Deterministic run reconstruction and invariant-violation audit of a @swamp/software-factory work item — stale SHAs across the artifact lineage, impossible states, unresolved critical/high blockers, and retained resources — rendered statically from recorded run data with no LLM involved, every flag traceable to the record it came from. Optional retained-worktree and external issue-tracker (Linear) correlation joins are pluggable, not required.

Initial release: deterministic run reconstruction + invariant-violation audit for @swamp/software-factory work items — stale SHAs, impossible states, unresolved blockers, and retained resources, with optional pluggable worktree/Linear joins.
