feat: add PR complexity scorer — estimate review effort\n\nImplements issue #135: a script that analyzes open PRs and computes\na complexity score (1-10) based on files changed, lines added/removed,\ndependency changes, and test coverage delta. Also estimates review time.\n\nThe scorer can be run with --dry-run to preview or --apply to post\nscore comments directly on PRs.\n\nOutput: metrics/pr_complexity.json with full analysis.\n\nCloses #135
