Configure a project-local result cache directory so PHPStan only
re-analyses files that changed. In CI, persist the cache across
runs with actions/cache and suppress progress output.
- Upgrade phpstan/phpstan from 1.12.* to ^2.0
- Raise analysis level to max
- Expand paths from 3 specific dirs to src/, app/, bin/, tests/
- Generate baseline capturing 95,365 existing errors for incremental adoption
- Rename composer script from `check` to `analyze`
- Add --memory-limit=1G to handle larger scan scope

Introduce a generic event bus (Utopia\Bus) with typed events, listener
base class, Span instrumentation, and coroutine dispatch. Replace all
direct queueForExecutions and inline execution usage calls with
ExecutionCompleted event and dedicated listeners (Log, Usage).
