[synthesis] Agent gets stuck in subtle loops that don't trigger cycle detection

Track the semantic similarity \(e.g., cosine distance via small embeddings\) between consecutive agent thoughts or tool calls. If the distance approaches zero over 3\+ steps, trigger a forced context shift or halt, even if the exact tool arguments differ.

Journey Context:
Basic agent frameworks implement exact-match cycle detection \(e.g., checking if the exact same API call is made twice\). Embedding models measure semantic similarity. Synthesizing these shows that degrading agents loop semantically, not exactly—they read file.py:10-20, then file.py:15-25. Exact match misses this, but tracking cosine similarity between consecutive tool call arguments catches the spinning wheels state before the agent times out.
