dsh-ops-linux: Self-maintained branch of dsh-ops for Linux/ARM64

dsh-ops-linux is a self-maintained branch of T-Auto/dsh-ops, maintained by SunsetRNE, targeting Linux/ARM64 (including Android) and DSH 0.2.2. It aims to reduce token consumption by replacing the official `read`, `glob`, and `grep` with compact, line-numbered tools, providing structured JSON tools and a typed SDK for 18 APIs for PTC mode, enabling the dynamic loading of advanced features via the reserved DSH `tools_addition`, and offering mode lines for discovery, compat, panel, and TUI. The article details the installation of the Linux branch using a local tarball, as well as marketplace and `npx` installation, dry-run, status checking, and uninstall commands for the upstream npm package `dsh-ops`. It also explains the purpose of the "8-line bundle" and highlights important considerations such as inconsistent version compatibility statements, the need to clean up configuration files, and issues regarding third-party branches and license checks.
