v0.11.0 — Phone notifications + on-pace band

New features

Phone notifications (ntfy.sh + shell command)

Get notified on your phone when:

• 5h session or 7d weekly reaches 90% (high usage warning)
• Limit reached (~100%) — with reset time
• Quota resets — new window starts

Open Notifications… from the tray menu to configure:

• ntfy topic: enter a topic name, subscribe to the same topic in the ntfy app on your phone
• Shell command: run any command on notification (supports {message}, {event}, {percent}, {quota} placeholders)
• Toggle each event type on/off independently

Zero-config: if ntfy/shell fields are left empty, only Windows balloons fire (existing behavior).

Grey on-pace band in the taskbar widget

The progress bars now show a grey ±5% band centered at the expected (linear-pace) usage for the current time window. This is the visual equivalent of the existing ▲/•/▼ pace glyph:

• Fill ends left of band → under pace (green ▼)
• Fill ends within band → on pace (yellow •)
• Fill ends right of band (band disappears) → ahead of pace (red ▲)
