feat: port dry TUI to Bubbletea v2

[moncho]

Replaces the entire tcell/gizak-termui rendering stack with Bubbletea v2, Bubbles v2, and Lipgloss v2, adopting the Elm architecture with a single top-level model that delegates to sub-models for each view. A shared TableModel provides cursor navigation, column sorting, text filtering, and scroll windowing across all list views. An overlay system handles the less viewer, confirmation prompts, text input, and menu. Docker events stream in with a 250ms debounce for live refresh. The old ui/termui/ package and legacy event-loop code have been removed entirely, going from ~16k lines down to ~6.5k.

Pull request overview

Ports dry’s TUI to Bubbletea/Bubbles/Lipgloss v2, removing the legacy tcell/termui rendering stack and adopting an Elm-style architecture with view sub-models and shared table behaviors.

Changes:

• Replaced the old termui/tcell UI widgets + event loop with Bubbletea v2 tea.Program and sub-models per view.
• Introduced new list/table-based models (containers/images/networks/volumes + swarm views) with filter/sort/navigation, plus overlay models (prompt, input prompt, menu).
• Updated theming/styling to Lipgloss v2 and removed golden/termui-based rendering tests and helpers.

SetWidth only updates the outer lipgloss container width, but the underlying textinput.Model keeps its own width for rendering/editing. This can lead to truncation/overflow or awkward cursor behavior. Consider calling m.input.SetWidth(w) (or w - lipgloss.Width(prompt) depending on desired UX) inside SetWidth.

Suggested change

	m.width = w
	m.width = w
	inputWidth := w - lipgloss.Width(m.input.Prompt)
	if inputWidth < 0 {
	inputWidth = 0
	}
	m.input.SetWidth(inputWidth)

When filtering is active, the header won’t reflect it: Filtered is set to TotalRowCount() and Filter isn’t passed. Align this with other models (e.g., containers/images) by using Filtered: m.table.RowCount() and Filter: m.table.FilterText() so the UI correctly displays filtered counts and active filter text.

[Copilot]

Same issue as NodesModel: Filtered should be the filtered row count (likely m.table.RowCount()), and the active filter text should be wired into the header (Filter: m.table.FilterText()). Otherwise the header won’t show filter state/count deltas.

[Copilot]

StacksModel supports filtering (FilterInputModel + SetFilter), but the header always shows Total → Total and never shows the filter text. Use Filtered: m.table.RowCount() and provide Filter: m.table.FilterText().

[Copilot]

Styles are derived from the global DryTheme, but there’s no guarantee they’ll be regenerated when DryTheme is rotated (the existing RotateColorTheme only swaps the pointer per the snippet). Consider updating RotateColorTheme() to call InitStyles() (or returning the new theme and having the app explicitly call InitStyles) to keep the UI consistent after theme changes.

[Copilot]

The name charple strongly implies a purple hue, but #D08850 is an orange/brown tone. Either adjust the hex value to match the intended palette color, or rename the variable so it reflects the actual color to avoid confusion when theming/tweaking.

Suggested change

	charple = lipgloss.Color("#D08850")
	charple = lipgloss.Color("#A550DF")

[Copilot]

This introduces time-based behavior (expiry) but there’s no accompanying unit test. Adding tests for (1) message visible before expiry, (2) cleared after expiry, and (3) empty/unset behavior will help prevent regressions; if you want deterministic tests, consider injecting a clock (e.g., now func() time.Time) into the model.

Suggested change

	func (m *MessageBarModel) SetMessage(text string, duration time.Duration) {
	m.text = text
	m.expiry = time.Now().Add(duration)
	}
	// Message returns the active message text, or "" if expired/unset.
	func (m MessageBarModel) Message() string {
	if m.text == "" || time.Now().After(m.expiry) {
	return ""

	now func() time.Time
