v1.16.15

[1.16.15] — 2026-04-07

Documentation mirror pass: bring zh-CN, ja, and ko READMEs to parity with the v1.16.7 English restructure (new 'Why qq' / 'なぜ qq か' / '왜 qq인가' pitch, How it works 4-layer breakdown, Install agent table, all 26 commands including bootstrap / post-design-review / design-research that were previously missing, tykit v0.5.0 + listener-thread main-thread recovery story, refreshed FAQ). docs/zh-CN/hooks.md fully rewritten to mirror docs/en/hooks.md from v1.16.14 — adds compile-gate, auto-pipeline-stop, auto-sync, SessionStart resume hints, qq_hook_input fallback note, and an Implementation Notes section. docs/dev/architecture/overview.md hook table extended to cover the same set, with a sentence about the jq → python3 fallback. docs/dev/core-roadmap.md drops the stale 'Unity is the current wedge / can later support Unreal, Godot, custom engines' framing — Godot, Unreal, and S&box are now at runtime parity through Python bridges, not future work — and the Engine Adapters listing enumerates all four current adapters.
