   Mixed positive/negative data is now auto-detected and rendered as a proportional split sparkline automatically — no flags required. Upward bars appear

   What's new in 1.0.0

   • Mixed positive/negative data is now auto-detected and rendered as a
     proportional split sparkline automatically — no flags required. Upward bars
     appear on top, downward bars below.
   • All-negative data now renders as inverted (downward) bars automatically.
   • New -n / --num-lines accepts three forms: a positive integer (total rows,
     allocated proportionally), 'auto' (smallest proportional row count), or
     'up:down' (explicit per-side layout). Integer and auto modes use a shared
     max scale; up:down uses independent per-side scaling.
   • New --zero flag: 'up' (default) places zeros on the positive baseline;
     'none' omits zeros from both sides.
   • Removed inverted=True / -i/--inverted and split=True / -s/--split from the
     public API. Inverted rendering is now an internal implementation detail.
   • Removed -v/--verbose CLI flag and verbose= parameter (were no-ops since
     introduction; never produced any output).
   • Proportional row allocation: up_rows/total == pos_max/range, so the zero
     line stays meaningful as the visual boundary between halves.
   • ANSI reverse video with complement block characters gives full 8-level
     resolution for downward bars. Falls back to top-fill Unicode characters
     (▔▀█) when NO_COLOR, ANSI_COLORS_DISABLED, or TERM=dumb is set.
   • Fixed: color emphasis (-e) in mixed positive/negative sparklines is now
     evaluated against the original values, not the abs-converted partition.
     Conditions like "blue:lt:0" now correctly match negative bars.
   • New index-slice form for -e/--emphasize: "color:[start:stop:step]" selects
     bars by position rather than value, using standard Python slice syntax
     (e.g. "red:[0:3]", "blue:[::2]", "yellow:[-1:]"). Value and slice
     expressions can be mixed freely.
   • Fixed: --wrap with mixed positive/negative data now correctly interleaves
     the positive and negative rows per window, rather than emitting all positive
     windows followed by all negative windows.
