XTester v.0.0.71

Manual price-scale zoom, clickable statistics, and historical data gap repair.

Chart:

• Manual price axis scaling: press and hold the left mouse button on the price scale and drag —
  down widens the range, up narrows it. While the manual scale is active, auto-fit is off;
  double-click the scale to return to automatic scaling. The chosen scale is remembered
  per symbol and timeframe.
• The crosshair is now drawn to the right of the current simulation time as well — across
  the entire visible area.

Strategy statistics:

• The equity chart legend is clickable: click "Strategy" or "Benchmark" to hide/show the series
  (the item turns gray but stays in place). At least one series is always visible — hide the only
  visible one and the other turns on automatically. The Y axis fits the actually visible series,
  including after auto-refresh.
• Removed the empty utility column on the left of the trades table — the table starts right at the data.

Data:

• Minute-gap repair for downloaded history: new tools find gaps in stored data and re-download them
  from the exchange; a registry of known exchange-side gaps (delistings/maintenance) avoids
  re-downloading them.
• History-loss protection on save: data on disk and in memory are merged instead of overwritten.

AI & service:

• AI commit message generation works with reasoning models (including local LM Studio ones):
  higher token budget, thinking is stripped from the answer, and an empty answer shows the reason
  instead of failing silently.
• Removed the false "crash report" prompt when starting after rebuilding from sources.
• English localization of the new messages (gap repair, chart errors).
