chore(release): 1.16.0 [skip ci]

# [1.16.0](https://github.com/asepharyana/mytheclipse/compare/v1.15.0...v1.16.0) (2026-08-29)

### Features

* round-13 abstractions — AggregateError for parallel fan-out ([ff5fbe4](https://github.com/asepharyana/mytheclipse/commit/ff5fbe49dc1ff06c287306835110a6652d6b24b9))

+# Implementation Spec: Round 12 — COMPLETE
+
+## Goal
+Self-healing resource pool (auto-reconnect) — remove per-call "is connection
+dead? rebuild" boilerplate.
+
+## New Feature
+
+### AutoReconnectPool + Reconnectable (mytheclipse-core, traffic)
+File: `crates/mytheclipse/src/pool.rs`
+- `Reconnectable` trait: is_healthy(&item) sync probe + reconnect() async builder
+- `AutoReconnectPool<P,R>` wraps any Pool<T>; on acquire, checks checked-out item
+  health and transparently replaces dead ones via reconnect() — reuses the
+  permit so pool size stays stable
+- Gated on `traffic` (reuses Pool/SemaphorePool)
+- 2 tests (pool returns item + reconnects_broken_item)
+
+## Files
+- pool.rs: +Reconnectable +AutoReconnectPool +test
+- lib.rs: export AutoReconnectPool, Reconnectable
+
+Build: exit 0. Tests: 0 FAILED. Clippy: 0 new warnings.

+File: `crates/mytheclipse/src/aggregate_error.rs`
+- Collects multiple `E: std::error::Error` from parallel/fan-out tasks into one

+- `empty()` / `with_context(..)` / push(E) / is_empty / len / iter
