// Workaround for Node 22 + @webex/internal-media-core.
//
// The bot framework transitively depends on `@webex/internal-media-core`, whose
// pre-compiled CJS bundle does `commonjsGlobal.navigator = { ... }` at import time.
// Node 22+ exposes `globalThis.navigator` as a non-writable property, so that
// assignment throws:
//
//   TypeError: Cannot set property navigator of #<Object> which has only a getter
//
// `--require` runs synchronously before any ESM resolution, which is the only
// hook early enough to fix the descriptor before the framework loads.
//
// We make the property writable + configurable, preserving any existing value
// so anything that reads from it later still works.

// Node version guard.
//
// Sendi runs .ts files directly via Node's native type-stripping loader,
// which is unflagged from Node 22.18. On older Nodes you get:
//     TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension ".ts"
// Fail loudly with an actionable message instead.
