[agent\_craft] Static few-shot examples become stale or irrelevant as the codebase evolves, causing the agent to use deprecated patterns

Replace static few-shot examples with dynamic retrieval: embed the current task description, query a vector DB of recent high-quality code commits or canonical examples from the \*current\* codebase, and inject the top-2 retrieved snippets as 'relevant examples' in the prompt.

Journey Context:
Standard few-shot prompting uses a fixed set of examples written at system design time. For coding agents operating on evolving codebases, this is a critical failure mode: the examples may use outdated APIs, deprecated libraries, or violate new style guides. The 'dynamic' approach treats few-shot examples as a retrieval problem. At query time, the agent embeds the user's intent \(e.g., 'add pagination to this query'\), retrieves the top-k most similar \*actual\* code snippets from the repo \(e.g., existing pagination implementations\), and uses those as few-shot examples. This ensures the 'style' and 'API usage' are current. This is distinct from RAG for documentation; this is 'In-Context Example Retrieval' \(ICER\). The tradeoff is latency \(embedding\+search time\) vs. relevance. This pattern is crucial for agents working on large, mature codebases where 'best practice' changes over time.
