docs: update documentation for PRs #59-63 refactors

- architecture.md: add chat system modules (src/ui/chat/), world map
  modules (src/rendering/world_map/), CatmullRomSpline (src/math/),
  transport decomposition, and updated namespace list
- status.md: update timestamp to 2026-04-14, add recent refactors
  section and world map known gaps
- CHANGELOG.md: add detailed entries for PRs #58-63 covering
  architecture, features, bug fixes, and 19 new test files
- TESTING.md: expand test suite layout from 8 to 27 files organized
  by category (core, animation, transport, world map, chat)
- CONTRIBUTING.md: update namespace table, testing section, and key
  files list to reflect new module directories
- README.md: update status timestamp to 2026-04-14
