Slop Code Cleanup

Aggressively clean up a codebase by eliminating eight distinct categories of code quality problems. Orchestrates eight specialized subagents that each own one cleanup category, so each one stays focused, deep, and fast — and so they can run in parallel on independent slices of the problem.

The philosophy is simple: a clean codebase has one clear way to do each thing. Duplication, weak types, unused code, hidden errors, and legacy fallbacks all create multiple paths where one would do. This skill hunts down those extra paths and removes them.

Repo Sync Before Edits (mandatory)

Before creating/updating/deleting files, sync the current branch with remote:

branch="$(git rev-parse --abbrev-ref HEAD)"
git fetch origin
git pull --rebase origin "$branch"

If the working tree is not clean, stash first, sync, then restore:
