Expand the popup to show everything the TUI does: period switcher submenu,
top activities with one-shot rate, top models, provider breakdown when more
than one provider has data, optimize findings, and an updated-timestamp row.
Add per-period Open Full Report so the terminal view matches what the popup
was showing.
For theme compatibility, stop hardcoding colors that don't work on both
light and dark GNOME themes. Keep the brand orange (#ff8c42) for the header
and findings, let everything else inherit the shell palette, and express
dimming through opacity instead of rgba so the popup reads correctly on
Yaru Light, Yaru Dark, Adwaita, Adwaita Dark, and any other theme.
Add a listener on org.gnome.desktop.interface color-scheme so the indicator
re-applies its .codeburn-dark / .codeburn-light class when the user flips
the system theme, without waiting for a reload.
Ship a GJS extension in extensions/gnome-shell/codeburn@agentseal.org so
GNOME users get the same panel-anchored popover Ubuntu's Quick Settings
uses, rather than the floating window the Tauri tray is limited to through
StatusNotifierItem.
The extension lives inside gnome-shell as a PanelMenu.Button, so it has
direct access to its own icon coordinates and can open a PopupMenu docked
under it without any IPC or DBus plumbing. The tradeoff is it only works
on GNOME 45+; the Tauri app in desktop/ stays the cross-platform option
for KDE, Unity, wlroots, and Windows users.
Data flow: the extension shells out to codeburn status --format menubar-json
every 60 seconds, parses the payload, and renders a header, top 5 activities,
and optimize findings count. Refresh and Open Full Report actions live in
the popup menu; the Open Full Report action spawns gnome-terminal with the
codeburn report TUI.
