test: add clipboard and notification rules tests

Adds 55 tests for clipboard store pure functions (detectLanguage for 12
languages + formatTimestamp with fake timers) and 13 tests for the
notification rules state machine (reconnect transition logic and no-op
handlers). Total test count now 698 across 30 files.

+ * - Queues and displays achievement notifications one at a time
+ * - Each notification shows the achievement's name, icon, description, and rarity
+ * - A gradient border and badge colour correspond to the achievement's rarity
+ *
+ * Manual testing checklist:
+ * - [ ] Achievement notification slides in from the right
+ * - [ ] Notification auto-dismisses after 5 seconds
+ * - [ ] Dismiss button works immediately
+ * - [ ] Multiple achievements queue and display sequentially
+ * - [ ] Legendary achievements have a yellow-orange gradient
+ * - [ ] Epic achievements have a purple-pink gradient
+ * - [ ] Rare achievements have a blue-indigo gradient
+ * - [ ] Common achievements have a green-emerald gradient

+/**
+ * HighlightedText Component Tests
+ *
+ * Tests the text-splitting logic used by the HighlightedText component,
+ * which highlights search query matches within a string.
+ *
+ * What this component does:
+ * - Splits text into an array of {text, isMatch} parts
+ * - Matches are case-insensitive
+ * - Special regex characters in the query are escaped
+ * - Non-matching text is preserved verbatim around matches
+ *
+ * Manual testing checklist:
+ * - [ ] Matching text is highlighted (yellow background) in the terminal
+ * - [ ] Highlighting is case-insensitive
+ * - [ ] Multiple matches on the same line all get highlighted
+ * - [ ] Non-matching text renders normally alongside matches

+ * StatusBar Component Tests

+ *
+ * What this component does:
+ * - Shows a coloured indicator dot for the connection state
+ * - Shows a text label for the connection state
+ * - Provides connect/disconnect buttons
+ * - Contains the working directory input and browse button
+ * - Houses all toolbar action buttons (settings, stats, panels, etc.)
+ *
+ * Manual testing checklist:
+ * - [ ] Green dot and "Connected" label when Claude is running
+ * - [ ] Animated yellow dot and "Connecting..." label whilst connecting
+ * - [ ] Red dot and "Error" label on connection error
+ * - [ ] Grey dot and "Disconnected" label when not connected
+ * - [ ] Directory input is hidden when connected, visible when disconnected
+ * - [ ] Connect button transitions to Disconnect button on connection

+ * - Supports filtering by language and search query
