fix(push): take the core push-open dedupe from posthog-android 3.65.0 and posthog-ios 3.75.0

[turnipdabeets]

Takes the push-open deduplication now built into the native SDKs, and drops the plugin-level copy.

posthog-android 3.65.0+ and posthog-ios 3.75.0+ count a PostHog notification tap once, whichever path reports it — the SDK's automatic capture or a manual capturePushNotificationOpened() call. The rule lives at the single choke point every path reaches, so the plugin no longer mirrors it.

What changes for developers: nothing to call differently. A manual capturePushNotificationOpened() for a PostHog-sent push already captured within the last 5 minutes (same invocation_id and action_id) is skipped instead of counted twice. A rerun of the workflow sends a new notification and counts separately. A push from another provider carries nothing to match on, so it is still counted once per report.

The Dart doc now also states the limit that follows from this: a manual call cannot enrich an automatic capture. Android's tray intent carries no notification text, so its automatic event has no $notification_title or $notification_body, and re-reporting the tap with them is skipped rather than merged.

posthog-android floor	3.64.0 → 3.65.2
posthog-ios floor	3.74.0 → 3.75.2

**Tests are not parameterised**

These tests repeat the same setup, remember, and membership checks across separate methods and inline input lists. This violates the repository directive to prefer parameterised tests and works against its OnceAndOnlyOnce rule. Please consolidate the matching, non-matching, and invalid-entry cases into parameterised tests before merging.

The code looks good; no qualifying findings. Verdict: correct.
