v0.2.0 — Ember

### Added

- Agent memory file (`.watchfire/memory.md`) — agents can persist project-specific knowledge (conventions, preferences, patterns) across sessions

### Changed

- Removed configurable "default branch" setting — tasks now merge into whatever branch is currently checked out in the project root

### Fixed

- macOS notifications now display the Watchfire icon instead of a generic system icon
- GUI terminal no longer duplicates output in an infinite loop when an agent stops
