/**
 * PLATFORM_FALLBACKS — DELETED in 4.0.8.
 *
 * Per the user-confirmed product decision (C1, 2026-08-03):
 *
 *   "Every caller resolution MUST go through the active IDE adapter.
 *    Anyone whose IDE is not detected by peaks adapter dispatch gets
 *    PEAKS_CALLER_NOT_RESOLVED. This is the desired product contract
 *    (vendor-neutral)."
 *
 * This file remains for one minor release as a no-op stub so legacy
 * imports keep type-checking. The named export is now an empty
 * readonly array; tests asserting `PLATFORM_FALLBACKS.length === 1`
 * updated in a follow-up slice — out of scope for the 4.0.8 contract
 * freeze).
 *
 * New code MUST NOT import `PLATFORM_FALLBACKS`. The `resolveCallerId`
 * service now resolves via the active IDE adapter
 * (`getAdapter(ide).resolveCallerId(env)`), with `PEAKS_CALLER_ID` /
 * `--caller-id <id>` as the vendor-neutral short-circuits.
 *
 * for the slice 4.0.8 contract.
