fix(api): model claude selalu pakai Opus dari settings.json, bukan deepseek

TUI turn.rs & daemon handler.rs ambil model langsung dari
settings.model (tersimpan 'deepseek-v4-flash-free' di
~/.local/share/zesdex/settings.json) padahal provider sudah 'claude'.

- feat(domain): resolve_effective_model() — saat provider claude, model
  diambil dari app_config provider claude (default_model=claude-opus-4-8
  hasil deteksi ~/.claude/settings.json), menang atas settings.model basi.
  Provider non-claude tetap hormati settings.model user.
- fix(tui): turn.rs pakai resolve_effective_model (bukan settings.model)
- fix(daemon): handler.rs run_turn + compaction pakai resolve_effective_model
- fix(data): ~/.local/share/zesdex/settings.json model deepseek -> claude-opus-4-8
- test: 3 unit test resolve_effective_model
