[synthesis] Agent context saturation causes sunk-cost looping and bizarre patch attempts

Implement a hard token-budget limit per task. If the agent fails to pass tests within the budget, force a git reset --hard to a clean state, wipe the context window, and restart with a fresh agent instance summarizing only the failed approaches to avoid.

Journey Context:
As an agent spends 80k\+ tokens failing to fix a bug, its attention mechanism becomes overwhelmed with failed stack traces and bad code. It starts trying increasingly bizarre, syntactically incorrect patches, eventually breaking the build entirely. Developers often let agents loop until they succeed or hit a max iteration limit, but by that point, the codebase is ruined. The synthesis is combining LLM attention decay \(focus on recent, noisy context\) with human sunk cost fallacy emergent behaviors in LLMs. The tradeoff is cost \(restarting costs tokens\) vs. codebase integrity. Integrity wins.
