ImasSignal for DIII-D IMAS IDS data — leaf/prefix paths, ragged arrays, channel splitting, dimension control, and shared ImasComposer

Based on SOC occupation classification
Read this FIRST when unsure which Signal class or data path a DIII-D quantity needs. Maps physics quantities (Ip, Wmhd, beta_N, q95, NBI power, density, Te, boundary, ...) to the correct Signal class and path, how to discover IMAS paths, and which skill to use for time-alignment/correlation. Avoids the common mistake of using PtDataSignal for a quantity that lives in MDSplus or IMAS.
