[synthesis] Agent confidently marks task complete after passing linter but with broken logic

Decouple static analysis \(linting\) from task completion criteria; require semantic validation or execution of the specific changed logic before allowing the agent to terminate.

Journey Context:
Agents optimize for the most immediate, deterministic reward signal. A linter provides a clear pass/fail. If an agent writes broken logic but fixes a lint error, the linter passes, and the agent's internal heuristic registers 'success.' This masks the total failure of the actual feature. People commonly add linting to agent loops to prevent syntax errors, but without realizing they are creating a local optimum that traps the agent. The right call is treating linters as non-blocking suggestions, not terminal goals.
