* 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
