Replace the cmux chevron mark with a Programa-branded icon: a dark terminal window with a tab strip (traffic lights + active/inactive tabs) and a glowing blue->purple prompt chevron and cursor. Authored as a full-bleed 1024 layer in the Tahoe AppIcon.icon (Icon Composer applies the platform shape, glass and shadow), and regenerated the AppIcon-Debug.appiconset PNGs to match.
Completes the icon swap: update icon.json to reference programa-terminal.png (the prior commit removed the old chevron asset) and regenerate the AppIcon-Debug.appiconset PNGs to the new design.

What this does
Replaces the old cmux chevron app icon with a Programa-branded one: a dark, skeuomorphic terminal window with a tab strip — traffic lights plus an active and an inactive tab — and a glowing blue→purple prompt chevron and cursor. It's designed to sit naturally next to macOS Terminal on Tahoe while reading as "tabbed terminal" at a glance.
Summary
AppIcon.icon(the macOS 26 / Icon Composer format used for Release): swapped the single chevron layer for a full-bleed 1024²programa-terminal.png. The window fills the canvas as one opaque, non-translucent layer; Icon Composer applies the platform superellipse mask, glass material, and drop shadow. Oldcmux-icon-chevron 2.pngremoved.Assets.xcassets/AppIcon-Debug.appiconset: regenerated all 10 PNGs (16–512 @1x/@2x) from the same artwork (pre-masked to the rounded shape, matching the macOS convention) so Debug builds show the new icon too.Test Plan
./scripts/reload.sh --tag app-iconbuilds clean (asset catalog +.iconcompile, BUILD SUCCEEDED).Notes / follow-up
AppIcon.appiconset(older-macOS fallback with light/dark/tinted variants) still carries the old art and already emits an "unassigned children" warning. It's out of scope here; updating that full light/dark/tinted set can be a follow-up if non-Tahoe support matters.icon.json+ the Debug PNGs). Squash-merge collapses them.
