Vaibhav Arora 8f35dcd128 fix(menubar): make provider strip reachable and mouse-wheel scrollable
Two related bugs in the macOS menubar `AgentTabStrip`:

1. With more detected providers than fit at the default 360pt popover
   width (~7+), the off-screen provider chips were unreachable. SwiftUI's
   horizontal `ScrollView` does not scroll from click-drag, and there
   was no other affordance to reveal the hidden tabs.

2. Independent mouse wheels could not scroll the horizontal strip.
   Standard wheels emit only vertical `deltaY` with
   `hasPreciseScrollingDeltas == false`, and a horizontal SwiftUI
   `ScrollView` ignores vertical-only deltas. Trackpads (which emit
   horizontal deltas natively) already worked.

Fix:

- Wrap the strip in `ScrollViewReader` and add overflow-aware
  left/right chevron buttons that programmatically scroll to the
  next/previous visible provider via `proxy.scrollTo(_, anchor: .center)`.
  Buttons only appear when `stripContentWidth > stripViewportWidth - 30`
  and disable at the ends.
- Install an `NSEvent.addLocalMonitorForEvents(matching: .scrollWheel)`
  in `.onAppear` (removed in `.onDisappear`). When the cursor is over
  the strip and the event is non-precise (`!hasPreciseScrollingDeltas`)
  with `deltaX≈0` and `deltaY≠0`, copy the `CGEvent` and transpose
  `scrollWheelEventDeltaAxis1` / `PointDeltaAxis1` / `FixedPtDeltaAxis1`
  onto axis 2 so the underlying NSScrollView receives a real horizontal
  delta.
- Track strip hover via a `@MainActor` singleton
  `AgentTabStripScrollState` so the local-monitor closure can read the
  latest hover status without capturing stale SwiftUI state.

Trackpad events are passed through untouched, so vertical scrolling
elsewhere in the popover is unaffected.

CodeBurn Menubar (macOS)

Native Swift + SwiftUI menubar app. The codeburn menubar surface.

Requirements

  • macOS 14+ (Sonoma)
  • Swift 6.0+ toolchain (bundled with Xcode 16 or standalone)
  • codeburn CLI installed globally (npm install -g codeburn) or available at a path you pass via CODEBURN_BIN

Install (end users)

One command:

npx codeburn menubar

That's it. The command downloads the latest .app from GitHub Releases, drops it into ~/Applications, clears Gatekeeper quarantine, and launches it. Re-running it upgrades in place with --force, or just launches the existing copy otherwise.

If you already have the CLI installed globally (npm install -g codeburn), codeburn menubar works the same way.

Build from source

For contributors running a local build instead of the packaged release:

npm install -g codeburn                       # CLI the app shells out to for data
git clone https://github.com/getagentseal/codeburn.git
cd codeburn/mac
swift build -c release
.build/release/CodeBurnMenubar                # launch

Build & run (dev against a local CLI checkout)

cd mac
swift build
# Point the app at your dev CLI build instead of the globally installed `codeburn`:
npm --prefix .. run build
CODEBURN_BIN="node $(pwd)/../dist/cli.js" swift run

The app registers itself as a menubar accessory (LSUIElement = true at runtime). No Dock icon.

Data source

On launch and every 60 seconds thereafter, the app spawns codeburn status --format menubar-json --no-optimize directly (argv, no shell) via CodeburnCLI.makeProcess and decodes the JSON into MenubarPayload. The manual refresh button in the footer invokes the same command without --no-optimize, which includes optimize findings but takes longer.

Override the binary via the CODEBURN_BIN environment variable (default: codeburn on PATH). The value is validated against a strict allowlist (alphanumerics plus ._/- space) before use, so a malicious env var can't inject shell commands.

Status

Live data wired. Next iterations:

  1. FSEvents watch for ~/.claude/projects/ changes (debounced refresh on real edits)
  2. Persistent disk cache for optimize findings so the default refresh can include them without the 30-second penalty
  3. Currency metadata in the JSON payload + Swift-side formatting
  4. Sparkle auto-update
  5. DMG packaging + Homebrew Cask tap
