DeepSeek TUI v0.8.39 Improves Mirror and Source Installs

What changed upstream

The current DeepSeek TUI install surface now gives a better answer to "how do I actually get this running on my machine or CI runner?" than many older tutorials:

• Latest stable moved again: the official Releases page now shows v0.8.39 as the newest stable tag.
• Mirror and fork controls are documented: the npm wrapper docs now list DEEPSEEK_TUI_RELEASE_BASE_URL for mirrored assets and DEEPSEEK_TUI_GITHUB_REPO for forked release sources, alongside force-download and CI-oriented install controls.
• CI failure handling is clearer: the install docs describe DEEPSEEK_TUI_OPTIONAL_INSTALL=1 so download failures do not always have to abort a matrix job.
• Windows and edge-platform guidance is stronger: the docs explicitly call out Scoop as a lagging package surface and include source-build guidance for musl, riscv64, FreeBSD, older ARM64 Linux targets, and Windows MSVC toolchains.
• Self-update troubleshooting is publishable: the install guide documents the older deepseek update aarch64 asset-name mismatch and points users to upgrade paths instead of leaving them with an opaque platform error.

Practical setup guidance

This is not just another patch-tag mention. It changes what a trustworthy DeepSeek TUI install page should cover:

1. Developers in mainland China or restricted corporate networks need an official mirror/fork path, not hand-wavy "try another proxy" advice.
2. Windows users need to know when Scoop is fine and when it can lag the GitHub release line.
3. CI maintainers need a documented way to avoid failing the whole install step on an optional postinstall download.
4. Edge-platform readers need a source-build answer grounded in upstream docs, not a guess.
