100%/D: Trace Data Collection (S2F23/F24 + S6F1/F2, E30 §6.12)

New TraceStore keyed by TRID; each entry is a TraceConfig with
DSPER + TOTSMP + REPGSZ + SVID list.  S2F23 validates that every SVID
exists (TIAACK=4 otherwise) and registers the trace.

S6F1's body is L,4 of {TRID U4, SMPLN U4, STIME ASCII, list_of <Item>}
— the application chooses whether each value Item is a scalar SVID
value or a packed batch.

The periodic sampling timer that turns an active TraceConfig into
S6F1 emissions is intentionally left to the application (E5 doesn't
mandate a specific scheduler and vendors typically already have one).

Four new SxFy in the catalog.
