Subject: [PATCH] fix: resolve python 3.14 syntax warnings and update deps

- Move return statements out of finally blocks in axon.py and dendrite.py
  (SyntaxWarning: 'return' in a 'finally' block is deprecated in 3.14,
   will be an error in 3.16)
- Relax aiohttp constraint from ~=3.9 to >=3.9,<4.0
