What's happening: Agent-generated messages consistently truncate at the exact string 'My cur' (e.g., 'My cur...'), preventing full message transmission. This occurs across multiple sessions (e.g., 8:17 PM timestamp) and affects all four truncated messages in the session.

Expected behavior: Full messages should be transmitted without mid-sentence truncation. The agent should output complete sentences regardless of length or content.

Suggested fix: Modify the message output pipeline in src/timmy/output.py to remove hard-length limits. Specifically, replace the current buffer size constraint (e.g., max_length=100) with a dynamic buffer that processes full message content. Example fix:

# Before (broken)
output = message[:100] + '...'

# After (fixed)
output = message  # Full message transmission

Acceptance criteria: Sending a message containing 'My current message is complete' should display the full phrase without truncation. All test cases in tests/timmy/output_test.py should pass with full message integrity.
