fix(macos): drop status item title while notch overlay is visible

The notch overlay wings already display elapsed time and step title;
keeping them on the status item too produced a duplicate readout
elsewhere in the menu bar.

+# Fail Well — macOS
+
+Menu bar + notch companion to the [Fail Well PWA](../). See [`see-this-pwa-and-proud-porcupine.md`](../../.claude/plans/see-this-pwa-and-proud-porcupine.md) for the design plan.
+
+## Requirements
+
+- macOS 15 Sequoia or later
+- Xcode 16 / Swift 6.0+ toolchain (`xcode-select --install` is enough — full Xcode not required)
+
+## Build & run
+
+```sh
+make run      # release build, packaged into FailWell.app, opened
+make debug    # debug build, packaged and opened
+make test     # swift test
+make clean    # remove .build and FailWell.app
+```
+
+The resulting `FailWell.app` lives next to the `Makefile`. It's an unsigned ad-hoc-signed bundle, fine for local use; for distribution you'd need a Developer ID.
