Problem Statement

The status bar shows context usage as plain text (ctx 4%). This is easy to miss during long sessions and
doesn't give quick visual feedback on how much context remains. I often glance down and miss it entirely.

Proposed Solution

Replace (or augment) the text percentage with a visual progress bar that changes color as usage increases:

Opus 4.6 ctx [████░░░░░░░░░░░░░░░░] 12% → green
Opus 4.6 ctx [████████████░░░░░░░░] 58% → yellow
Opus 4.6 ctx [████████████████░░░░] 80% → orange
Opus 4.6 ctx [████████████████████] 98% → red

Color thresholds:

• 0-50%: green
• 50-75%: yellow
• 75-90%: orange
• 90-100%: red

Alternative Solutions

Currently I just watch the small text percentage, which is easy to overlook. No good workaround exists.
