chengyongru afc8d50659 test: add comprehensive tests for consolidate offset functionality ...

Add 26 new test cases covering:
- Consolidation trigger conditions (exceed window, within keep count, no new messages)
- last_consolidated edge cases (exceeds message count, negative value, new messages after consolidation)
- archive_all mode (/new command behavior)
- Cache immutability (messages list never modified during consolidation)
- Slice logic (messages[last_consolidated:-keep_count])
- Empty and boundary sessions (empty, single message, exact keep count, very large)

Refactor tests with helper functions to reduce code duplication by 25%:
- create_session_with_messages() - creates session with specified message count
- assert_messages_content() - validates message content range
- get_old_messages() - encapsulates standard slice logic

All 35 tests passing.
