Introduces type specialization for reactive pipeline nodes and their data buffers. This eliminates the overhead of generic `Value` enums and `SharedValueSeries` when dealing with known scalar or record types. The architecture shifts buffer instantiation from the VM to the runtime (RTL), leveraging type information from the AST. A new `out_type` field is added to `BoundKind::Pipe` to store the static type of the pipeline's output, determined by the type checker. This enables the creation of specialized `RingBuffer<T>` and `SharedRecordSeries` (for Struct-of-Arrays layout) when the output type is known, significantly improving memory usage and processing speed for time-series data, especially in financial analysis.
