/**
 * Agent-directory scanner: enumerates per-agent skill and subagent
 * directories declared by the existing `AgentRegistry`. Each occurrence
 * carries an `agent-dir` discriminator parameterized by `agentId` and the
 * subject `type`.
 *
 * Subject coverage in v1:
 *
 * - skill — every agent with a non-empty `agent.skills.dir`.
 * - subagent — every agent with `agent.subagents?.dir`. Single-file
 *   subagent surfaces (`isFile === true`, e.g., `roo`'s `.roomodes`) emit one
 *   occurrence per file path; the file itself is the materialization.
 *
 * Rules: no agent in the v1 `AgentRegistry` exposes a rules directory, so the
 * scanner emits no rule occurrences.
 *
 * Each occurrence carries structural fields the subject modules need for
 * cross-platform path handling — `pathSegments` (the absolute path split via
 * the `Path` service) and `subjectFile` (the canonical primary file inside
 * the subject directory) — plus a probed `subjectFileExists` flag so subject
 * modules do not hardcode presence.
 *
 * Per Decision 5, scanner output is occurrence-shaped. The public effect
 * carries no `FileSystem | Path` requirement; per-file partial failures
 * publish diagnostic warnings rather than failing the cell.
 *
 * The scanner avoids `fs.stat` and uses only `fs.exists` / `fs.readDirectory`
 * so it remains compatible with the fixture builder's in-memory `FileSystem`.
