/**
 * Agent-settings scanner: enumerates per-agent native settings files (e.g.,
 * `.claude/settings.json`, `.cursor/settings.json`).
 *
 * Per Decision 5, scanner output is occurrence-shaped. Each occurrence
 * represents one observable settings file — present and readable on disk —
 * keyed by `agentId`. The per-file payload is intentionally not parsed here:
 * Phase 8's per-agent modules decode the typed `nativeConfig` shape through
 * their own schemas. The scanner's contract is "this agent has a settings
 * file at this absolute path", not "this settings file is well-formed".
 *
 * Per-file partial failures (e.g., unreadable directory) become diagnostic
 * warnings rather than errors. The error channel stays empty.
