refactor: move all app code to internal/termapp and entry to cmd/
Consolidate remaining package main files into internal/termapp for clean separation: cmd/serialterminal/ is the sole entry point. Update .goreleaser.yaml to build from ./cmd/serialterminal. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
