Key architectural milestones in git history

• 64-byte Cell packing (d85b6d4): Expanded Grapheme::data to char data[36] (44 bytes total for Grapheme) and added uint8_t reserved[5] to Cell with static_assert(sizeof(Cell) == 64).
• Third-pass audit & CI hardening (a6c3d49, 389b62c, 51c6c1d): Added pointer-collision tracking (state_ptr and has_custom_id on FocusTarget), host termination signal handler chaining (N3), 500 ms / 4 MB bracketed paste timeout (N4), and the Clang < 19.0 __cpp_concepts=202002L CMake definition.
• Second-pass review & headless suites (520626e, 7c98289): Added std::array<Constraint, N> layout overloads, word-boundary wrapping in Text::wrap(), modal target pruning in FocusManager::pop_scope(), hidden-widget skipping in FocusManager::next()/prev(), and modularized the headless test suite into 6 CTest targets.
• Zero-allocation LayoutResult & audit C-01..C-36 (19bb0a3, 039b2a1): Introduced the 16-element stack-buffered LayoutResult, unified Color value conversions, and added SGR text attributes (TextAttr).
• Focus system & spatial hit-buffer (5785412..e66fd25): Added koto::Id, Frame hit-buffer tagging and bounding-box harvesting, FocusManager, 2D spatial arrow navigation, and IdScope modal trapping.
