[pseudoseed]

The fork shipped upstream's outside sinks: server usage events to PostHog through ingest.t3.codes (on by default, key baked in), T3 Connect relay traces to Axiom from server, web, and mobile, and mobile crash reports and launch timings through expo-observe.

Each is disabled at one point, so callers and settings stay as upstream has them and no build config or baked key can turn one back on:

• AnalyticsService.layer is a no-op.
• relayTracing.layer never builds an OTLP exporter.
• Mobile Observe endpoint is https://observe.invalid and dispatching is configured off; the "Send crash reports" toggle is removed.

UI copy and docs now say nothing is sent. docs/internals/product-analytics.md lists the 3 choke points for future upstream syncs. User-configured OTLP export to your own receiver is unchanged.

Tests: the web runtime and mobile tracing tests now assert no request is made even with trace credentials set. vp run check:changed passes.
