[katsugtgz]

Updates aiohttp to address GHSA-5wr8-gcqf-gqf3, GHSA-2g87-pp6c-29x5, and GHSA-494j-54xm-rwp3.

Evidence:

• requirements.txt referenced aiohttp@3.14.3
• osv-scanner reported those three IDs for aiohttp 3.14.3 before the update
• updated version: aiohttp==3.14.4

Validation:

• osv-scanner no longer reports any advisory for aiohttp after the update, and no new advisories were introduced
• pip install -r requirements.txt succeeds on Python 3.13 and import aiohttp reports 3.14.4

Scope: dependency pin update only. ccxt requires aiohttp<3.15,>=3.14.3, so 3.14.4 stays within that range.
