read_file does not decode UTF-16 LE files created by Windows PowerShell 5.1

[lAiasu]

Using powershell.exe (Windows PowerShell 5.1) as the shell, redirected output is written as UTF-16 LE:

@("alpha", "beta", "gamma") *> $env:TEMP\dc-utf16-test.txt

Reading that file with read_file returns text containing embedded NUL characters.

This causes tool-result persistence to fail with PostgreSQL error 22P05: \u0000 cannot be converted to text.

Reproduction

1. Set defaultShell to powershell.exe.
2. Run:

@("alpha", "beta", "gamma") *> $env:TEMP\dc-utf16-test.txt

3. Call read_file on dc-utf16-test.txt.
4. The returned text contains NUL characters between letters.

Expected

read_file should detect the UTF-16 BOM and decode the file as UTF-16 LE.

Additional result

The same command does not reproduce with pwsh.exe (PowerShell 7), which writes UTF-8 output by default.

Tested with Desktop Commander 0.2.44 on Windows 11.
