0.8

Added

• PowerShell output (#7): shell="powershell" on to_curl() / to_curl_async() renders curl.exe --% … for Windows PowerShell 5.1, quoted by Windows command-line rules so arbitrary JSON survives. Without the stop-parsing token, 5.1's argument binder mangles the body however it is escaped; on pwsh 7.2+ run $PSNativeCommandArgumentPassing = 'Legacy' first, and note that %NAME% references in a payload are expanded. Constants curlify3.SH and curlify3.POWERSHELL are exported; default shell="sh" output is unchanged.
• End-to-end shell tests (test_shell_e2e.py): the generated command is run by a real shell — bash, plus powershell.exe and pwsh on a new windows-latest CI job — against a local server that checks the request arrives byte-for-byte.
