Add active and active-plus-critical floatbar modes - #296
Conversation
Pinned providers stay the default. Active shows the provider for the focused supported app or terminal agent. Active plus critical also keeps providers at the warning threshold. An unrelated window keeps the last active provider. Detection is local and can be turned off.

📝 WalkthroughWalkthroughThe floating bar now supports pinned, active, and active-plus-critical provider modes. Local foreground detection matches supported applications and terminals, tracks the last active provider, and updates visible providers through persisted settings.

A cwd named cursor or codex was treated as the focused agent. Only the title prefix before a path separator is used, and the leftmost agent name wins.

Keep the pinned list until a match exists. Prefer an agent title inside Warp. Recognize Windows Terminal Preview. Use the catalog id for OpenCode Go. Strip mixed-case .exe names. Do not put window titles on the event, and read the focused window off the async runtime.

Medium Risk
Changes float bar visibility logic and adds periodic foreground process inspection on Windows; non-Windows builds cannot detect focus, so active modes may not behave as users expect outside Windows.
Overview
Adds Pinned, Active, and Active + critical modes for which providers the floating bar shows. Pinned stays the default and unchanged behavior.
Active shows only the last matched provider for the focused supported desktop app or a terminal whose title hints at an agent. Active + critical keeps that provider and also any pinned providers at or above the high-usage warning threshold. If focus is unrelated or unknown, the bar keeps the last active provider instead of clearing.
On Windows, the Tauri backend polls the foreground window (~750ms), maps process path and title to a provider id (Ceiling itself and VS Code are not auto-mapped to Copilot), caches last active, and emits
foreground-provider-changed. The float bar listens and callsget_foreground_provideron mount. Detection is local only—no provider API calls—and can be turned off while staying in an active mode.New persisted settings
floatBarSelectionModeandfloatBarForegroundDetectionflow through the bridge, float bar settings UI (with locale strings), andselectVisibleFloatBarProvidersin the React float bar. Foreground watching is not implemented off Windows (read_foregroundis a stub), so active modes there rely on cached last-active state until/unless detection is added.Reviewed by Cursor Bugbot for commit 4cd18ff.
