fix: pass resolved config to staged scan to preserve ancestor inheritance

The staged scan materializes files to /tmp, where loadConfig's ancestor
traversal would never find a monorepo root's config. Now the CLI resolves
config from the real project directory first and passes it via the new
configOverride ScanOption, so customRulesOnly, share, ignore rules,
and textComponents all apply correctly during --staged scans.
