fix: upgrade posthog-node to v5 to fix missing telemetry events

[AmanVarshney01]

Summary

• Upgrades posthog-node from 4.18.0 to 5.28.2 to fix a bug where captureImmediate didn't properly await the HTTP request, causing telemetry events to be silently dropped before process.exit()
• Removes deprecated captureMode and persistence constructor options that no longer exist in v5

Root cause

In posthog-node v4, captureImmediate() had a missing return in a .then() chain, so the promise resolved before the HTTP request completed. Since trpc-cli calls process.exit() after the handler finishes, the in-flight request was killed. This is fixed in v5.
