chore(rust): bump posthog-rs to 0.19.2

[cat-ph]

Problem

The Rust workspace pins posthog-rs 0.19.1. The 0.19.2 patch release fixes default in-app frame classification for error tracking:

• Cargo dependency sources are recognized by cargo's on-disk layouts under any CARGO_HOME (e.g. /usr/local/cargo in the official Rust Docker images), not just ~/.cargo, so dependency frames stop being marked as app code in containers.
• Crate-denylist matching strips trailing generic arguments before extracting the crate name, so DWARF-derived names like poll_future<tokio::runtime::...> classify correctly.
• Fileless thread/process bootstrap symbols (__clone, start_thread, _start, etc.) are classified as not in-app.

Release notes: https://github.com/PostHog/posthog-rs/blob/main/CHANGELOG.md

Changes

• Bump posthog-rs from 0.19.1 to 0.19.2 in rust/Cargo.toml and rust/Cargo.lock. No API changes.

How did you test this code?

• cargo check -p posthog -p cymbal -p batch-import-worker (the three crates consuming posthog-rs) passes.
