Implementation Spec: Round 13 — COMPLETE

New Feature

AggregateError (mytheclipse-core, resiliency)

File: crates/mytheclipse/src/aggregate_error.rs

• Collects multiple E: std::error::Error from parallel/fan-out tasks into one error — natural failure type for join_all + batch/fan-out resilience
• empty() / with_context(..) / push(E) / is_empty / len / iter
• from_results(Vec<Result<V,E>>) -> Result<Vec<V>, AggregateError> — collects ALL errors, returns values when all Ok
• Display lists count + first error; From<Vec<Box>>, Extend
• 3 tests
