Plot Title Collisions

When multiple plot() (or hline()) calls share the same title, PineTS disambiguates them by appending a #N suffix to the plot key. The first plot keeps the plain title, and subsequent collisions are numbered sequentially:

First plot(close, "SMA") → plot key "SMA"
Second plot(open, "SMA") → plot key "SMA#1"
Third plot(high, "SMA") → plot key "SMA#2"

Using duplicate plot titles is not recommended. The #N suffix ordering depends on execution order and may lead to fragile references. Always prefer unique titles for each plot. A more elegant solution for this case will be provided in a future version of PineTS.
