Two-phase manifest handling for ecosystems and package managers

API

// Phase 1: Detection (cheap) - find manifests, identify package manager
manifests, err := ecosystem.DetectManifests(dir)

// Phase 2: Parsing (expensive) - extract dependencies
for _, m := range manifests {
    parsed, err := ecosystem.ParseManifest(m, repoRoot)
}

Package Manager Detection

Detection infers PackageManager from lockfile presence in the manifest directory (searching upward to repo root). Each ecosystem defines its own lockfile-to-manager mapping.
