feat: software-engineering skill v0.5 (G7/G8 ops + iteration)

Stacked on v0.3 + v0.4 (HEAD d6522ba feat-full-auto): v0.3/v0.4
content preserved, not reverted. Adds G7 post-release ops and
observation (monitoring, errors, cost/quota, feedback, hotfix loop,
rollback triggers, ops manual) and G8 iteration and scaling (v1.1
handover list, contract v1->v2 protocol, new-end onboarding,
scale/performance, deprecation), with G6->G7 and G7->G8 gates,
DAG, gate table, coordinator derivation, G0-G8 todos, checklist,
09-ops and 10-iteration role templates, and ops-manual / v1.1
handover templates in both body and appendix. Settles web+React+
multi-viewport focus, cross-viewport E2E, web single-end release
with iOS/Android native postposed, open-source-first, and the
TypeScript full-stack default (user-request-only language change;
codex-app-server itself stays Python). Pending #199 and #205
merge, then one rebase round. PR only, do not merge or deploy.

+热修复与回滚触发、跨视口 E2E、开源优先与许可证口径、
+TypeScript 默认栈与用户特别要求例外、iOS/Android 后置。
