Diagnosing stack-trace symbolication

Symbolication is the cross-platform name for what JavaScript source-map lookup, Hermes function-offset resolution, Proguard / R8 demangling, and dSYM address-to-line lookup all do — turn a minified or obfuscated frame back into a readable file, function, and line.

Work through the user's build and PostHog symbol sets as one pipeline: build config -> generated symbol artifacts (JavaScript source maps, Hermes maps, Proguard mappings, or dSYM bundles) -> uploaded symbol set in PostHog -> captured error frame. Most failures become obvious once those four pieces are checked in order.
