Dead Code Cleanup with Repowise

Repowise detects dead code through graph analysis — no LLM needed, works even with a template-rendered wiki.

When the user asks about dead/unused code

Call get_dead_code() to get findings sorted by confidence tier. Useful parameters:

safe_only=true — only findings confirmed safe to delete (confidence >= 0.7)
kind="unreachable_file" — files with no importers
kind="unused_export" — public symbols nobody uses
kind="zombie_package" — monorepo packages with no consumers
directory="src/old/" — limit to a specific directory
tier="high" — only high-confidence findings (>= 0.8)
min_confidence=0.7 — raise the floor (default is 0.5) for a release-ready cleanup
group_by="directory" or group_by="owner" — roll up to see where the dead code concentrates and who owns the most of it
