Improve documentation information architecture

Restructure the Read the Docs sidebar navigation from 3 imbalanced
sections (API/Guide/Tutorials) into 6 balanced sections:

- Getting Started: quickstart, choosing estimator, troubleshooting
- Tutorials: Fundamentals: core DiD methods (basic, staggered, synthetic, etc.)
- Tutorials: Advanced Methods: specialized estimators (TROP, imputation, etc.)
- Tutorials: Study Design: diagnostics & power analysis
- Comparisons & Benchmarks: R/Python comparisons and validation
- API Reference: grouped into Estimators, Diagnostics, Results, Data

Also adds GitHub notebook links to all tutorial pages via nbsphinx_prolog,
updates llms.txt documentation structure to match new IA, and bumps
llms-full.txt version to 2.7.2.
