dsh-pwsh-encoding-fix

On Chinese Windows, native programs disagree on output encoding: ipconfig and javac write GBK, while node, Maven 3.9+, and Gradle 9 write UTF-8. DSH's pwsh tool decodes everything as UTF-8 by default, so any single fixed interpretation leaves half the programs garbled. dsh-pwsh-encoding-fix resolves this conflict at the source.

Inside the PowerShell process, the plugin switches the console encoding to Latin-1, a strictly one-byte-per-codepoint scheme that preserves every byte written by native programs without loss. After capture, each segment is heuristically decoded: strict UTF-8 is attempted first, falling back to the system ANSI code page on failure. Mixed GBK and UTF-8 output within a single command is handled segment by segment, and the result is re-emitted as UTF-8 so the Node-side collector decodes it correctly. Command exit codes ($LASTEXITCODE) are preserved, the wrapper works for both foreground run and background start, and only the PowerShell executor is affected.

This plugin is ideal for developers on Chinese Windows who use DSH's pwsh tool alongside encoding-sensitive tools such as ipconfig, systeminfo, javac, node, Maven, or Gradle, and want a permanent fix for garbled output without manually switching chcp or guessing each program's encoding.
