fix(windows): GUI subsystem + parent-console attach + canonical muyue.exe (v0.7.5)
Three Windows install/launch issues reported by the user:

1. Double-click on Desktop shortcut → dialog "This is a command line
   tool. You need to open cmd.exe and run it from there."
   Cause: charmbracelet/huh detects no TTY when launched via Explorer
   and aborts. Fix:
   - cmd/muyue/commands/root.go: skip RunFirstTimeSetup when
     os.Stdin is not a character device; persist config.Default()
     and let the React onboarding wizard handle first-run UX.
   - ci-{main,develop}.yml: build Windows binaries with
     -ldflags="-H=windowsgui" so the .exe is a GUI subsystem app —
     no console window flashes on double-click.

2. CLI sub-commands (`muyue scan`, `muyue install-shortcuts`, etc.)
   would lose all output under -H=windowsgui when launched from
   cmd.exe / PowerShell. Mitigation:
   - cmd/muyue/console_windows.go (new, build-tagged): on init(),
     call kernel32!AttachConsole(ATTACH_PARENT_PROCESS). If the
     parent has a console, rebind os.Stdout/os.Stderr/os.Stdin to
     it and call log.SetOutput(os.Stderr) so existing log.Printf
     calls surface. If no parent console (Explorer), exit silently.

3. After install, `muyue` not recognized in PowerShell.
   Causes: (a) the extracted binary is muyue-windows-amd64.exe, not
   muyue.exe; (b) the user PATH update by install-shortcuts doesn't
   propagate to the existing PowerShell session.
   Fix in install-shortcuts:
   - Copy self to <installDir>/muyue.exe (rename impossible — the
     running .exe is locked on Windows) so `muyue` resolves once
     PATH is set.
   - Update Desktop + Start Menu .lnk to target the canonical
     muyue.exe rather than the platform-suffixed binary.
   - Print the line `$env:Path += ';<installDir>'` for the user to
     paste, refreshing the current session immediately.
   - ci-main.yml install snippet bumps to 5 lines, last being
     `$env:Path += ";$dest"`.

- internal/version/version.go: 0.7.4 → 0.7.5
- CHANGELOG.md: v0.7.5 entry covers all three fixes
