Commit Message

feat(ucalc): representable value histogram command (#634) (#662)

Add `histogram [lo, hi, bins]` that shows distribution of representable
values across user-specified bins with ASCII bar chart.

Default 20 bins, configurable 1-1000. Reuses numberline's enumeration
and estimation infrastructure. Skips gracefully for high-precision
types (double, fp128) where enumeration is infeasible.

Example:
  fp8e4m3> histogram [0, 1, 10]
  [   0,   0.1) ######################################## 29
  [ 0.1,   0.2) ########### 8
  [ 0.2,   0.3) ###### 5
  ...
  representable values: 57

All output formats: plain (ASCII bars), --json, --csv, --quiet.

Resolves #634
