## Title

    Proposed fix: [Amp CLI npm (@ampcode/cli, formerly @sourcegraph/amp)] 'Error: Amp native binary not installed.' / '[@ampcode/cli] Unsupported platform: linux x64' on Alpine/musl and Windows arm64

## Body

    Recommended action: Allow postinstall scripts (or run `node install.cjs` in the package dir), don't omit optional deps, or use `node <pkg>/cli-wrapper.cjs` as a fallback; on Alpine use a glibc-based image; prefer the install method in Amp's docs; switch dependencies from @sourcegraph/amp to @ampcode/cli.
    
    Option: Allow postinstall scripts (or run `node install.cjs` in the package dir), don't omit optional deps, or use `node <pkg>/cli-wrapper.cjs` as a fallback; on Alpine use a glibc-based image; prefer the install method in Amp's docs; switch dependencies from @sourcegraph/amp to @ampcode/cli. [evidence: official_recommended_action]
    Applies when: Installing Amp via npm/pnpm/bun or in Alpine containers
    Steps:
    1. Reinstall with scripts enabled: npm install -g @ampcode/cli.
    2. pnpm/bun: allow @ampcode/cli build scripts / trustedDependencies.
    3. Use a glibc base image instead of Alpine.
    Expected: The error no longer appears.
