test: strengthen assertions across 3 more test files (batch 2)

Browse Source 
test_run_agent.py (2 weak → 0, +13 assertions):
  - Session ID validated against actual YYYYMMDD_HHMMSS_hex format
  - API failure verifies error message propagation
  - Invalid JSON args verifies empty dict fallback + message structure
  - Context compression verifies final_response + completed flag
  - Invalid tool name retry verifies api_calls count
  - Invalid response verifies completed/failed/error structure

test_model_tools.py (3 weak → 0):
  - Unknown tool error includes tool name in message
  - Exception returns dict with 'error' key + non-empty message
  - get_all_tool_names verifies both web_search AND terminal present

test_approval.py (1 weak → 0, assert ratio 1.1 → 2.2):
  - Dangerous commands verify description content (delete, shell, drop, etc.)
  - Safe commands explicitly assert key AND desc are None
  - Pre/post condition checks for state management
