v2.0

New Features:

1. Context Compression
   • Compresses the agent's working memory when the context exceeds a configurable token threshold.
   • Prevents redundant tool calls across long retrieval loops. Tunable via BASE_TOKEN_THRESHOLD and TOKEN_GROWTH_FACTOR.

2. Agent Limits & Fallback Response
   • Introduced hard caps on tool invocations (MAX_TOOL_CALLS) and reasoning loop iterations (MAX_ITERATIONS) to ensure bounded execution.
   • When either limit is reached, the agent falls back to a dedicated response node, using all context retrieved so far to generate the best possible answer rather than failing silently.

Improvements:

1. Enhanced Notebook Documentation
   • Expanded and clarified comments for each code block, including references to official documentation.
   • Improves readability and helps users better understand each pipeline component.
