Add BarChart component that renders multi-row Unicode bar charts with
anchored Y-axis labels, automatic tick-step computation, sub-sampling
for narrow terminals, and optional X-axis date labels. The chart
gracefully degrades to a sparkline when width/height is too small.
Add ContentCard, CardRow, and CardInnerWidth utilities for consistent
bordered card layout across all dashboard tabs. ContentCard renders
a lipgloss-bordered card with optional bold title; CardRow joins
pre-rendered cards horizontally; CardInnerWidth computes the usable
text width after accounting for border and padding.
Add LayoutRow helper that distributes a total width into n integer
widths that sum exactly, absorbing the integer-division remainder
into the first items -- eliminates off-by-one pixel drift in multi-
column layouts.
Refactor MetricCard to accept an outerWidth parameter and derive the
content width internally by subtracting border, replacing the old
raw-width parameter that required callers to do the subtraction.
MetricCardRow now uses LayoutRow for exact width distribution.
Refine TabBar to render all tabs on a single row when they fit within
the terminal width, falling back to the two-row layout only when
they overflow.
Simplify StatusBar by removing the unused filterInfo append that was
cluttering the left section.
Implement shared UI components used across the dashboard tabs:
- tui/components/card.go: Three components:
* MetricCard: bordered card with label (muted), value (bold), and
optional delta (dim) — used for the dashboard's top-level KPIs.
* MetricCardRow: renders N cards side-by-side using lipgloss
horizontal join, auto-calculating card width from available space.
* Sparkline: theme-colored Unicode block sparkline (8-level,
auto-scaled to series max). Used in Dashboard and Trends tabs.
* ProgressBar: filled/empty bar (accent + dim) with percentage
label. Used in the Budget tab for plan-relative spend.
- tui/components/statusbar.go: Bottom status bar with left-aligned
keybinding hints ([f]ilter [?]help [q]uit), current filter info,
and right-aligned data age indicator. Padding auto-fills to
terminal width.
- tui/components/tabbar.go: 10-tab navigation bar split across two
rows (Dashboard/Costs/Sessions/Models/Projects on row 1,
Trends/Efficiency/Activity/Budget/Settings on row 2). Each
inactive tab highlights its keyboard shortcut letter with [bracket]
notation. Active tab renders in accent color. Settings uses 'x'
as its shortcut (not present in the name, so appended). TabIdxByKey
maps key presses to tab indices.

Implement the theming layer for the interactive dashboard:
- tui/theme/theme.go: Theme struct with 14 semantic color roles
(Background, Surface, Border, BorderHover, TextDim, TextMuted,
TextPrimary, Accent, Green, Orange, Red, Blue, Purple, Yellow).
Four built-in themes:
* Flexoki Dark (default): warm, low-contrast palette designed for
extended reading. Teal accent (#3AA99F) on near-black background.
* Catppuccin Mocha: pastel warm tones with blue accent (#89B4FA)
on dark surface (#1E1E2E).
* Tokyo Night: cool blue/purple palette with blue accent (#7AA2F7)
on deep navy (#1A1B26).
* Terminal: ANSI 16-color only for maximum compatibility — maps
all roles to standard terminal colors (0-15), works correctly
in any terminal emulator regardless of true-color support.
Global Active variable holds the current theme. SetActive/ByName
enable runtime theme switching from the settings tab and setup
wizard.
