* Configurable legend position (Top/Left/Right/Bottom) and vertical text (GitHub #9023)
- Add LegendPosition enum and legendPosition, legendVerticalText to MolDrawOptions
- Support legend at Top, Left, Right, Bottom; vertical text for Left/Right
- Python: MolDrawOptions.legendPosition, .legendVerticalText; LegendPosition enum
- Python: MolToSVG() wrapper with legend/drawOptions; doc updates for MolToImage
- JSON: legendPosition (string), legendVerticalText (bool) in draw options
- C++ and Python tests; release note and Cartridge.md docs
* MolDraw2D: legend gutter for horizontal side legends; vertical side height fit
- Reserve horizontal gap between molecule and left/right horizontal legends
(scale mol to molWidth-gutter, align toward legend strip).
- Position horizontal side legend by measured text width from partition edge.
- Vertical side legends: iterative scale so n*max_h+(n-1)*gap fits panel.
- Catch: long vertical side legend section.
* Update legend-position tests and review-driven cleanup
Use enum/default wording for legendPosition docs, move the lightweight Python test to Wrap, add regex-based placement checks (including horizontal side and vertical stacking), and refactor extractLegend helpers per style guidance.
* Fix MolDraw2D legend edge cases
* MolDraw2D: review follow-up (legend tests, bounds, DRY Top/Bottom)
* Update no-FT legend test coords
* Address PR review: document constants, remove release-note text, and simplify extra-padding logic
