docs: replace all ASCII/Unicode diagram blocks with matplotlib SVG figures
Replace 23 ASCII/Unicode text diagram code-blocks in mathematical_foundations.md
with professionally rendered matplotlib SVG figures.
Changes:
- Add docs/source/_gen_diagrams.py: Python script generating all 23 SVG figures
with consistent styling (white bg, blue/orange/green/red palette, scipy/numpy/
matplotlib Agg backend)
- Add docs/source/_static/diagrams/*.svg: 23 rendered SVG figures covering:
§1 DE/random-walk/BM/GBM, §2 Ito/Picard/FP/EM/OU, §3 Poisson/Merton/Levy,
§6 Kalman, §7 MCMC, §9 KL/Fisher, §10 curvatures/natural-gradient
- Update mathematical_foundations.md: all ASCII art code-blocks replaced with
MyST {figure} directives pointing to the generated SVGs
- Sphinx build: clean success, all 23 SVGs copied to build, 1 pre-existing warning
Resolves: user request for professional publication-quality figures instead of
ASCII/Unicode art (which was too low-level for publication)
