docs: integrate publication analysis — Alexa, Bobenko, Springborn, Crane, Lutz
Add phases 9d / 9e / 9f and literature citations derived from a systematic
review of the five authors' publication lists (Tier 1 / 2 / 3 analysis).
phases.md:
- Phase 9d: ConesUtility port (9d.1) + non-Euclidean cone extensions
(9d.2, RESEARCH) + StereographicUnwrapper (9d.3)
- Phase 9e: CirclePatternLayout + CirclePatternUtility (Java port)
- Phase 9f: Polygon Laplacian on non-triangular meshes (Alexa 2011/2020,
RESEARCH — no Java equivalent)
- Phase 9b-analytic: add Rivin-Springborn 1999 as Schläfli source
- Phase 10b: add Bobenko-Bücking 2009 + Bobenko-Lutz 2024 IMRN
- Phase 10c: add Lutz 2023 (canonical tessellations) + Bobenko-Lutz 2024
- Phase 10c' KoebePolyhedron: add Bowers-Bowers-Lutz 2026 rigidity result
