Jose Olarte III 7d87a746f9 feat(ios): register Swift TimeSafariNativeFetcher for New Activity notifications
Add TimeSafariNativeFetcher (plansLastUpdatedBetween parity with Android) and
call DailyNotificationPlugin.registerNativeFetcher from AppDelegate before JS
configureNativeFetcher; broaden DailyNotificationDelivered scheduled_time types
in willPresent. Wire the new file into the App target; normalize PBX object IDs
to 24-char hex.

Document plugin ≥3 handoff (consuming-app-handoff-ios-native-fetcher-chained-dual),
refresh iOS/Android parity and notification-from-api-call file tables.

# Consuming app handoff: iOS native fetcher + chained dual (mirror)
**Canonical source:** `daily-notification-plugin` repo, `doc/CONSUMING_APP_HANDOFF_IOS_NATIVE_FETCHER_AND_CHAINED_DUAL.md` (same content as below for offline use).
---
## Implemented in this app
- **`ios/App/App/TimeSafariNativeFetcher.swift`** — Swift `NativeNotificationContentFetcher` mirroring `TimeSafariNativeFetcher.java` (`POST …/plansLastUpdatedBetween`, starred IDs from `daily_notification_timesafari.starredPlanIds`, JWT pool selection, pagination key `daily_notification_timesafari.last_acked_jwt_id`, aggregated copy).
- **`AppDelegate.swift`** — `DailyNotificationPlugin.registerNativeFetcher(TimeSafariNativeFetcher.shared)` at launch **before** any JS `configureNativeFetcher`; foreground handler reads `scheduled_time` as `Int64`, `NSNumber`, or `Int` for `DailyNotificationDelivered`.
## Dependency
- **`@timesafari/daily-notification-plugin`** must be **≥ 3.0.0** (register native fetcher, chained dual, iOS `updateStarredPlans`). Declare it in `package.json` from the official remote (`git+https://gitea.anomalistdesign.com/trent_larson/daily-notification-plugin.git`, branch or tag as needed), then `npm install` so `package-lock.json` resolves the published tree.
## Bump / sync (after plugin version is resolved)
1. `npm install`
2. `npx cap sync ios && npx cap sync android`
3. `cd ios/App && pod install`
4. Clean build in Xcode / Android Studio
## QA focus
- iOS: Fetcher registered before `configureNativeFetcher`; `updateStarredPlans` not `UNIMPLEMENTED`.
- Both: New Activity fires **after** prefetch for that cycle where the plugin implements chaining.
- Android: Existing `MainActivity.setNativeFetcher` unchanged; regression-test `cancelDualSchedule` vs Daily Reminder.

## Original handoff text (from plugin)
This document is for the **host app** repository (e.g. crowd-funder-for-time-pwa) after bumping `@timesafari/daily-notification-plugin` to a version that includes:
- **iOS** `NativeNotificationContentFetcher`style registration (`DailyNotificationPlugin.registerNativeFetcher`)
- **iOS** `updateStarredPlans` / `getStarredPlans` (parity with Android `daily_notification_timesafari` / `starredPlanIds` semantics)
- **iOS** chained dual flow: user notification is **armed only after** prefetch completes (delay if fetch is late; max slip 15 minutes before fallback copy)
- **Android** chained dual flow: exact **notify** alarm is scheduled **after** dual prefetch completes (no longer scheduled at initial `scheduleDualNotification` before fetch)
Material from `doc/new-activity-notifications-ios-android-parity.md` still applies; the plugin doc adds **app-side** steps not spelled out there.
### 1. iOS — register native fetcher before `configureNativeFetcher`
The plugin **rejects** `configureNativeFetcher` if no fetcher is registered (aligned with Android).
**In `AppDelegate` (or earliest app startup before Capacitor calls into the plugin):**
```swift
import TimesafariDailyNotificationPlugin
DailyNotificationPlugin.registerNativeFetcher(TimeSafariNativeFetcher.shared)
```
Implement **`TimeSafariNativeFetcher`** as a Swift type that:
- Conforms to `NativeNotificationContentFetcher`
- Implements `fetchContent(context: FetchContext) async throws -> [NotificationContent]` with the same **Endorser** behavior as `TimeSafariNativeFetcher.java`
- Implements `configure(apiBaseUrl:activeDid:jwtToken:jwtTokenPool:)` if the fetcher needs credentials pushed from TypeScript
**Starred plan IDs for the fetcher:** Read JSON array string from UserDefaults key **`daily_notification_timesafari.starredPlanIds`** (written by `updateStarredPlans` from JS).
### 2. iOS — `UNUserNotificationCenterDelegate` / rollover
Chained dual notifications set:
- `notification_id` = `org.timesafari.dailynotification.dual`
- `scheduled_time` = `NSNumber` (fire time in ms)
Ensure **`DailyNotificationDelivered`** forwards **`notification_id`** and **`scheduled_time`** from **notification content `userInfo`**.
### 3. Android — no API change for `setNativeFetcher`
Host apps that already call `DailyNotificationPlugin.setNativeFetcher(TimeSafariNativeFetcher(...))` keep that flow.
**Behavior change:** the dual **notify** alarm is scheduled when **dual prefetch work finishes**, not at the initial `scheduleDualNotification` only.
### 4. Assumptions
- Swift host implements `TimeSafariNativeFetcher`; the plugin does **not** embed `plansLastUpdatedBetween` on iOS when a host fetcher is registered (mirrors Android).
- Module import: `TimesafariDailyNotificationPlugin` (Pod `TimesafariDailyNotificationPlugin`).
