Improvements

[nmaguiar]

This pull request updates the documentation to highlight recent enhancements to Mini-A's tool orchestration, caching, and reliability features. The changes clarify new options for performance tuning, describe resilience improvements, and provide configuration guidance for advanced tool usage and fault tolerance.

Tool orchestration and caching improvements:

• Added documentation for parallel tool execution, smart context caching, deterministic tool result caching (using MCP metadata like annotations.readOnlyHint, annotations.idempotentHint), and lazy MCP initialization via the mcplazy option. Default and per-tool cache TTLs can now be configured using toolcachettl. [1] [2] [3]

Reliability and recovery upgrades:

• Documented new reliability features: exponential backoff for LLM/MCP calls, automatic checkpoints and restoration, error categorization (transient vs. permanent), MCP circuit breakers, and persistent error summaries. These features are enabled by default and can be observed with verbose/debug logging. [1] [2]

Configuration guidance:

• Updated the configuration section to explain the new mcplazy and toolcachettl options for fine-tuning tool orchestration and caching behavior.
• Clarified how deterministic tool result caching works and how tools advertise determinism through MCP metadata.
