<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Mostly tooling and workflow changes; primary risk is CI/build failures
if npm 11.8.0 or strict engine checks conflict with some environments.
> 
> **Overview**
> **Standardizes npm version/engine enforcement.** Adds `.npmrc` with
`engine-strict=true` and updates `package.json`/`package-lock.json`
`engines` to require `npm` `11.8.0`.
> 
> **Updates automation to match.** CI, release, and deflake workflows
now install `npm@11.8.0` before running `npm ci`, and a new `.claude`
command (`fast-push`) documents an autonomous commit/lint/amend/push/PR
flow.
