Incorporates README, architecture doc, and Java ConformalLab source
structure. Adds:
- Long-term CGAL package goal made explicit
- Language policy: all code/comments/docs in English
- Java-to-C++ porting table (what is done, what is Phase 9, what is Phase 10)
- Java class names as reference anchors for future porting work
- "Natural theta" and gradient-check test patterns
- Halfedge traversal conventions
- CI job table with expected pass/skip counts
- Both remotes (origin + Codeberg) sync requirement
- Known quirks (Finder duplicates, protected main, Boost header-only)

Covers build commands (all three modes), single-test invocation,
header-only architecture, the three geometry modes, Newton solver
sign conventions, layout BFS design, test patterns, CI structure,
and known quirks (Finder ` 2.hpp` duplicates, CGAL compile flags).
