fix(cli): report the default channel when native config has none

[giaBaoJS]

hot-updater channel reports an empty channel on any project that has never had
a channel written into its native files, even though the app is running on
production.

Cause

getChannel builds its result by layering the parser output over a default:

return merge(
  { value: DEFAULT_CHANNEL },
  await androidParser.get("hot_updater_channel"),
);

es-toolkit merge only leaves the target value in place when the source value is
undefined. A null source value is copied over:

merge({ value: "production" }, { value: null,      paths: [] }) // { value: null }
merge({ value: "production" }, { value: undefined, paths: [] }) // { value: "production" }

AndroidConfigParser.get and IosConfigParser.get return { value: null } when
the key is absent, so the production default is always discarded in exactly the
case it exists for. Both platforms are affected
(packages/hot-updater/src/utils/setChannel.ts).

Effect

init does not write a channel, so this is the state of a project until someone
runs hot-updater channel set. handleChannel passes the value to
ui.channel, which renders an empty value as -:

Channels
    Android:  -
    Path:     android/app/src/main/AndroidManifest.xml
    iOS:      -
    Path:     ios/HotUpdaterExample/Info.plist

That is misleading rather than merely blank: with no channel in the native
config, HotUpdaterImpl falls back to DEFAULT_CHANNEL = "production" on both
Android and iOS, so the app really is on production. After the fix the command
prints production for both platforms.

Change

Fall back with ?? instead of merge, so only a genuinely absent value is
replaced. Added setChannel.spec.ts covering both platforms plus the
already-configured case; the two fallback tests fail on main with
value: null.

pnpm lint, pnpm test:type and pnpm test all pass (169 files, 2162 tests).
