fix(core): free UvLoopInner on uv_loop_t drop to prevent worker memory leak (#33200) ## Summary - Add `Drop` impl for `uv_loop_t` to free the `UvLoopInner` allocation that was previously leaked on every Web Worker teardown - Each worker's `JsRuntime` creates a `uv_loop_t` via `uv_loop_init`, which heap-allocates a `UvLoopInner` (~9 KB of HashMaps, BTreeSets, Vecs). When the runtime was torn down, `OpState::clear()` dropped the `Box<uv_loop_t>` but the raw `internal` pointer to `UvLoopInner` was never freed — `uv_loop_close()` was never called - This caused RSS to grow linearly with worker count (~40 KB/worker on macOS, ~25 KB/worker on Linux including allocator fragmentation) ### Before (RSS grows linearly, never plateaus) ``` After 500 workers: RSS=162.0 MB (+59.9 MB) After 1000 workers: RSS=169.1 MB (+67.0 MB) After 1500 workers: RSS=177.1 MB (+75.0 MB) After 2000 workers: RSS=183.2 MB (+81.0 MB) ``` ### After (RSS plateaus after warmup) ``` After 500 workers: RSS=153.3 MB (+56.8 MB) After 1000 workers: RSS=155.5 MB (+59.0 MB) After 1500 workers: RSS=156.6 MB (+60.1 MB) After 2000 workers: RSS=157.6 MB (+61.1 MB) ``` macOS `leaks` tool confirmed: 2177 leaked objects (917 KB) → 382 (48 KB) after 100 workers — **93% reduction** in leaked bytes.
