 * One-time migration for the agent/task/hive/swarm stores that historically lived
 * under `<projectCwd>/.monomind/<subpath>` (via getProjectCwd()) before being
 * consolidated onto the canonical getMonomindDataRoot() location (typically
 * `<repo>/.git/monomind/<subpath>`). Several MCP tool files (agent-tools.ts,
 * hive-mind-tools.ts, swarm-tools.ts, system-tools.ts) used to read/write the
 * legacy path directly, causing the same logical store to physically split from
 * task-tools.ts/session-tools.ts, which always used getMonomindDataRoot().
 *
 * If the canonical file is missing but the legacy file exists, copy (never move,
 * for safety) the legacy file into place so pre-existing data isn't silently
 * orphaned. Best-effort and idempotent — never throws, and it's a no-op once the
 * canonical file exists or when the two paths already coincide (e.g. no .git).
 *
 * @param canonicalPath Absolute path under getMonomindDataRoot() the tool now reads from.
 * @param legacySubpath Path relative to `.monomind/` that the tool used to read from
 *   (e.g. `join('agents', 'store.json')`).
 * @param cwd Optional project cwd override (defaults to getProjectCwd()).
