Add comprehensive unit tests for Ctrl+C behavior

- test_single_ctrl_c_stops_agent: Verifies first Ctrl+C stops agent gracefully with helpful message
- test_double_ctrl_c_raises_keyboard_interrupt: Verifies second Ctrl+C within 2 seconds raises KeyboardInterrupt for CLI cleanup
- test_ctrl_p_pauses_agent: Verifies Ctrl+P still pauses agent as expected

Tests use proper mocking of prompt_toolkit's create_input, raw_mode, and attach context managers.
All tests pass and validate the improved Ctrl+C behavior implementation.

+Unit tests for ConversationWindowCondenser.
+
+These tests mirror the tests for `_apply_conversation_window` in the AgentController,
+but adapted to test the condenser implementation. The ConversationWindowCondenser
+copies the functionality of the `_apply_conversation_window` function as closely as possible.
+
+The tests verify that the condenser:
+1. Identifies essential initial events (System Message, First User Message, Recall Action/Observation)
+2. Keeps roughly half of the non-essential events from recent history
+3. Handles dangling observations properly
+4. Returns appropriate CondensationAction objects specifying which events to forget
