/**
 * Shared Zod fragments for tool schemas.
 *
 * Many tool files declare identical `platform` / `deviceId` fields. This
 * module centralises them so the platform list (sourced from
 * `BUILTIN_PLATFORMS` in `device-manager.ts`) cannot drift between files.
 *
 * Behavioural contract:
 *   - `platformEnum` — optional platform string, described as "Target
 *     platform. If not specified, uses the active target.". Enum values
 *     come from `BUILTIN_PLATFORMS`.
 *   - `deviceIdField` — optional device id string with the canonical
 *     multi-device description.
 *
 * Files with intentionally narrower platform sets (e.g. autopilot, a11y)
 * keep their own enums and only reuse `deviceIdField`.
