refactor: Phase 7 - TUI cleanup - reorganize model package
Phase 7 of the monorepo maintainability plan:
New files created:
- model/jobs.go - Job type, JobStatus constants, list.Item interface
- model/messages.go - tea.Msg types (JobsLoadedMsg, StatusMsg, TickMsg, etc.)
- model/styles.go - NewJobListDelegate(), JobListTitleStyle(), SpinnerStyle()
- model/keys.go - KeyMap struct, DefaultKeys() function
Modified files:
- model/state.go - reduced from 226 to ~130 lines
- Removed: Job, JobStatus, KeyMap, Keys, inline styles
- Kept: State struct, domain re-exports, ViewMode, DatasetInfo, InitialState()
- controller/commands.go - use model. prefix for message types
- controller/controller.go - use model. prefix for message types
- controller/settings.go - use model.SettingsContentMsg
Deleted files:
- controller/keys.go (moved to model/keys.go since State references KeyMap)
Result:
- No file >150 lines in model/ package
- Single concern per file: state, jobs, messages, styles, keys
- All 41 test packages pass
