Triggered by a Telegram report from a Chinese user trying to deploy
DeepSeek TUI on a HarmonyOS ARM64 thin-and-light: `npm i -g deepseek-tui`
exited with `Unsupported architecture: arm64 on platform linux` because
v0.8.7 only published x64 Linux artifacts. They worked around it with
`cargo install`, but the README never documented that path for ARM users.
This PR closes that gap on three layers:
- **Release workflow** — add `aarch64-unknown-linux-gnu` to the build
matrix using GitHub's `ubuntu-24.04-arm` runner. v0.8.8 will publish
`deepseek-linux-arm64` and `deepseek-tui-linux-arm64` alongside the
existing x64/macOS/Windows assets, plus add the row to the Release
body's manual-download table.
- **npm wrapper** — uncomment the linux/arm64 row in `ASSET_MATRIX`,
rewrite the `Unsupported architecture/platform` error to print the
full `cargo install deepseek-tui-cli deepseek-tui --locked` recipe
and link to docs/INSTALL.md, and add `DEEPSEEK_TUI_OPTIONAL_INSTALL=1`
so CI matrices that include unsupported platforms can keep running
without a binary.
- **Docs** — new docs/INSTALL.md covering every supported platform,
prebuilt vs. cargo install vs. manual download, cross-compiling x64
-> ARM64 with `cross` or `gcc-aarch64-linux-gnu`, China mirror setup,
and a troubleshooting section for the common arm64, MISSING_COMPANION_BINARY,
and self-update arch-mapping (#503) errors. README and README.zh-CN
now have an explicit Linux ARM64 quickstart pointing at `cargo install`
for v0.8.7 today and `npm i -g` for v0.8.8+; the v0.8.7 known-issue
block is updated to mention both #503 and the missing arm64 prebuilt.
