fix: make playback work on Windows

[joshkerr]

Summary

Three independent fixes that together make cue usable on Windows. I hit these in order trying to play a movie with mpv (installed via scoop) on Windows 11.

1. Plex JSON decoder rejects boolean stream flags

Plex now returns stream flags (default, forced, selected, external) as JSON booleans on some servers, but plex.Stream declared them as int. ResolvePlayable failed with:

json: cannot unmarshal bool into Go struct field Stream...default of type int

…which surfaced in the TUI as a generic "failed to parse response" when pressing play. Fixed by introducing a flexBool type that accepts both forms.

2. No Windows path in the player launcher

detectPlayer only handled darwin / linux, so on Windows it fell through to launchDefault, which ran xdg-open — not a thing on Windows. Added a windowsPlayers list (mpv, vlc) and switched the default fallback to cmd /c start "" <url>.

3. mpv IPC used Unix domain sockets

net.Dial("unix", …) doesn't work on Windows — mpv's --input-ipc-server uses named pipes there. The scrobbler degraded gracefully (warn + exit-only reporting), so playback worked but live progress and 90%-auto-mark-watched did not.

Split mpvipc.go into:

• mpvipc.go — shared mpvConn type and methods
• mpvipc_unix.go (//go:build !windows) — existing Unix-socket dial + %TEMP%/cue-mpv-<ns>.sock path
• mpvipc_windows.go (//go:build windows) — winio.DialPipe against \.\pipe\cue-mpv-<ns>

Also broadened the mpv-command check in launchConfigured so mpv.exe and paths with backslashes enable IPC. Added /cue.exe to .gitignore.

Adds one new dependency: github.com/Microsoft/go-winio v0.6.2.

Test plan

• go build ./... on Windows
• go vet ./... on Windows
• go test ./... on Windows — all packages pass
• Cross-compile GOOS=linux go build ./...
• Cross-compile GOOS=darwin go build ./...
• Manual smoke test on macOS / Linux that mpv IPC progress reporting still works (unchanged code path, but worth confirming on a real system)
• Manual smoke test on Windows 11 with scoop mpv + Plex: playback launches, IPC connects, progress is reported

Hi @joshkerr

The changes look good, Just wanted to confirm: Does playback on windows work after fixing these?

[joshkerr]

Yes. It works fine.
