[FEATURE] Publish linux-arm64-android native binary for Termux

Summary

Claude Code v2.1.113+ does not work on Android/Termux because the native binary for linux-arm64-android is not published, even though the platform mapping already exists in install.cjs and cli-wrapper.cjs.

Current State

• install.cjs and cli-wrapper.cjs already include linux-arm64-android and linux-x64-android in the PLATFORMS map
• But the native binary package @anthropic-ai/claude-code-linux-arm64-android is not published to npm
• The glibc-compiled linux-arm64 binary segfaults on Android kernel via Termux glibc-runner (tested on aarch64, Android 15)
• Workaround: pin to v2.1.112 (last JS-only version), but this means missing 85+ versions of updates

What I Am Requesting

Publish the @anthropic-ai/claude-code-linux-arm64-android binary package so that npm install -g @anthropic-ai/claude-code works on Termux/Android the same way it does on Linux.

Why This Matters

• Termux is a full Linux userspace on Android with glibc-layer support (glibc-runner)
• Many developers use Termux on tablets/chromebooks as their primary coding environment
• Claude Code WORKED on Termux before v2.1.113 (see #50270, #51741, #71878) — this is a regression
• The platform mapping code already exists; only the binary build/target is missing

Related Issues

• #50270 — primary open issue about v2.1.113+ breakage on Termux
• #51741 — duplicate, closed
• #71878 — Remote Control broken after Node.js 24 upgrade on Android
• #50307 — same issue on OpenBSD (also closed as not planned)

Environment

• Device: Android aarch64, Termux
• Node.js: v24.15.0
• npm: 11.16.0
• glibc-runner: v2.0 (installed)
