feat: add workflow visualization with FlowDisplay and bump version to 2.2.77

- Added execute_sync_callback call in custom LLM path to match OpenAI behavior
- Fixed issue where Gemini/custom LLM responses were not triggering callbacks
- Prevents duplicate display by relying on LLM class to handle verbose display
- Ensures both paths execute callbacks for consistent behavior

The issue was that custom LLM providers (like Gemini) were not calling
_execute_callback_and_display after guardrail validation, while OpenAI
path was. This caused missing Task/Response display boxes for Gemini.

-# Ollama Handling in LLM.py
-
-The `ollama_handled` flag is used in `llm.py` (not in `agent.py`) to track whether special Ollama model handling has been applied for tool results. Here's what I found:
-
-## Where it's used in llm.py:
-- **Line 863**: `ollama_handled = False` - initialized at the beginning of the tool execution loop
-- **Line 864**: Special handling logic via `_handle_ollama_model()` method
-- **Line 907**: `ollama_handled = True` - set when Ollama special handling is applied
-- **Line 928 & 959**: Checks `if not ollama_handled` to avoid duplicate processing
-
-## Why it's needed:
-The flag prevents duplicate processing when Ollama models require special handling. Some Ollama models return only the tool call JSON without processing the results, requiring a follow-up prompt to get the final answer. The `ollama_handled` flag ensures this special handling happens only once.
-
-## Does this contradict the requirement?
-**No, it doesn't.** The issue states:
-
-> "ollama/xxxx model is already handled via llm.py via litellm, so no special condition or handling required for ollama inside agent.py"
-
-✅ **Current implementation is correct:**
-
-- `agent.py` has NO ollama-specific conditions (only one documentation mention as an example)
-- All ollama handling is contained within `llm.py` as intended
-- The `ollama_handled` flag is an internal implementation detail within `llm.py`
-
-The codebase already follows the desired pattern where ollama models are handled through the generic LLM interface via litellm without special conditions in agent.py.
