Build Failure Log Retrieval And Analysis With Context Extraction

** - Enable AI Agents to fix build failures from CircleCI.

Unique: Combines CircleCI API integration with project detection system that works from local git context, allowing agents to fetch failure logs without explicit project configuration, and includes structured log parsing to extract actionable error patterns rather than raw text.

vs others: Provides deeper context extraction than CircleCI's native UI or basic API clients by parsing logs into structured failure patterns and supporting project auto-detection, enabling LLM agents to reason about failures without manual configuration.
