docs(D.5.2): retire IA-16, add IA-18/AP-43..45, roadmap + memory
Divergence register:
- Retire IA-16 (item-icon composite PARTIAL — D.5.2 now complete).
- Add IA-18 (effect overlay = ReplaceColor tint SOURCE, faithful retail
behavior; anti-regression guard — do NOT re-implement as a blit layer;
cites IconData::RenderIcons 0x0058d180 + ReplaceColor 0x00441530).
- Add AP-43 (effect tint = mean-opaque color; exact retail byte
decompiler-ambiguous, visual/cdb confirmation pending).
- Add AP-44 (effects==0 black-fallback recolor skipped; regression-risk
avoidance, pending visual/cdb confirm).
- Add AP-45 (0x02CE sequence byte not honored, latest-wins).
Section header counts updated: IA 15→17, AP 41→44.
Roadmap: mark D.5.2 shipped (419c3ac..2f789da; appraise dropped as no-op;
effect recolor + live 0x02CE).
Tests: update ToolbarControllerTests iconIds lambda arity 4→5 to match the
D.5.2 GetIcon signature change (was caught by the build).
Memory: project_d2b_retail_ui.md updated with D.5.2 shipped entry
(via claude-memory symlink to ~/.claude/projects/.../memory/).
