chore: add fallow dev dependency, scripts, and minimal config

Adds the fallow codebase-intelligence analyzer as a devDependency with
`pnpm fallow` (full scan) and `pnpm fallow:audit` (changed-files gate)
scripts and a minimal .fallowrc.json (entry points + duplicate-clone
threshold). Ignores the .fallow/ cache dir.
