chore(deps): bump muxcore v0.21.6 -> v0.21.19

[thebtf]

Bumps github.com/thebtf/mcp-mux/muxcore from v0.21.6 to v0.21.19.

Changes (v0.21.7–v0.21.19)

All 13 releases are graceful restart fixes for Windows AF_UNIX (issue #99):

• v0.21.7: propagate DaemonFlag to successor process
• v0.21.8: defer control socket binding in handoff mode
• v0.21.9: defer shutdown until after control response write
• v0.21.10: flush conn before afterFn to prevent data loss
• v0.21.11: guarantee response delivery before process exit (WaitGroup)
• v0.21.12: half-close write side before peer-drain
• v0.21.13: replace peer-drain with Close + delay (Windows AF_UNIX workaround)
• v0.21.14: diagnostic build (phase markers)
• v0.21.15: fix d.mu deadlock during graceful restart
• v0.21.16: unconditional stale socket remove in runDaemon
• v0.21.17: remove stale owner sockets during handoff restore
• v0.21.18: use SendWithTimeout for graceful-restart in upgrade
• v0.21.19: consolidation release, remove 50ms Sleep workaround

Verification

• go build ./... — clean
• go vet ./... — clean
• go test ./... — all pass

Стихотворение

🐰 Зависимостей танец, версии летят,
Обновим мукс до двадцать-девятнадцать спешат,
Токенизер и регекс уходят в небосвод,
Чистота в коде живёт, новый путь нас ждёт! ✨
