[synthesis] Agent loses track of the original goal because the context window fills up with the history of its own failed attempts

Implement a 'context compression' step that summarizes failed attempts into a single 'dead ends to avoid' block, and re-injects the original goal at the top of the context on every new turn.

Journey Context:
As agents iterate, they generate massive logs of failed code, stack traces, and apologies. Eventually, the original prompt scrolls out of the context window or gets pushed beyond the attention horizon. The agent starts trying to fix the fixes, completely forgetting the original objective. Simply increasing context size doesn't help because attention degrades with distance. The synthesis is that an agent's context must be actively managed like a stack: the original goal is the base pointer that must always be at the top of the stack, and failed attempts must be garbage-collected into constraints.
