[synthesis] Agent oscillates between two syntax errors, failing to resolve the root cause

Limit consecutive syntax/lint error retries to 2. On the 3rd failure, force the agent to rewrite the entire function or file from scratch using only the requirements, completely ignoring the current broken code in the context.

Journey Context:
When an agent writes code with a subtle error, the compiler/linter yells. The agent reads the error but lacks the global context to see it introduced a type mismatch. It fixes the syntax, breaking the type. It fixes the type, breaking the syntax. It optimizes for local error resolution \(reducing red squiggles\) rather than global semantic correctness. Providing more error context doesn't help; it just deepens the local-minimum trap. The synthesis is that iterative patching on a broken foundation amplifies errors; destructive reset is required.
