specify init hangs on Windows (PowerShell 5.1) after writing files

[carlosaparrag]

Environment

• OS: Windows (PowerShell 5.1)
• specify version: 0.10.1 (also tested 0.10.2.dev0)
• Install via uv tool install specify-cli

Steps

1. mkdir testdir && cd testdir
2. specify init --here --force --ignore-agent-tools --script ps

Expected

Scaffolding completes and exits.

Actual

Hangs indefinitely after ASCII banner and "Specify Project Setup" box. No further output. Must kill process.

Notes

• specify version, specify check, specify version --features work fine
• Files ARE written to disk despite the hang (25+ files created in .specify/)
• Same result with --integration copilot, --integration opencode
• Empty and non-empty directories both hang
• Stdin closed, env vars, Process.Start all hang
