inotify leaks

**Still seeing Failed to create DNS resolver channel… spam on aiodns== 3.5.0 with pycares 4.10.0**

After upgrading from aiodns==3.2.0/aiohttp==3.11.18 to aiodns==3.5.0 + aiohttp==3.12.15 + pycares==4.10.0, logs fill with:
`Failed to create DNS resolver channel with automatic monitoring of resolver configuration changes. This usually means the system ran out of inotify watches. Falling back to socket state callback. Consider increasing the system inotify watch limit: Failed to initialize c-ares channel`

**Environment:**
```
Ubuntu 22.04.5 LTS, Python 3.13.1
uvloop==0.21.0
aiohttp[speedups]==3.12.15
aiodns==3.5.0
pycares==4.10.0
aiohttp-socks==0.10.1
```

**Workload:** many short-lived ClientSessions; some requests via ProxyConnector(..., rdns=False)

Problem starts at `aiodns==3.3.0`

I don't yet understand how to reproduce the problem locally, but in the production environment the error appears every time

**I use this code for requests:**
```
async with aiohttp.ClientSession(
json_serialize=orjson.dumps,
timeout=aiohttp.ClientTimeout(total=9, connect=1.5, sock_connect=1.5),
connector=ProxyConnector.from_url(f"http://{proxy}", rdns=False),
) as sess:
async with sess.get(
```
