Replace overly broad `except Exception` catches with specific exception types to improve error handling clarity and debugging: - subtensor_interface.py: Handle both TimeoutError and asyncio.TimeoutError for substrate initialization timeout (resolves TODO comment) - utils.py (is_valid_github_url): Catch ValueError, TypeError, AttributeError for URL parsing exceptions (resolves TODO comment) - utils.py (normalize_hyperparameters): Catch KeyError, ValueError, TypeError, AttributeError for parameter normalization - wallets.py (new_hotkey): Catch ValueError, TypeError for Keypair.create_from_uri - wallets.py (new_coldkey): Catch ValueError, TypeError for Keypair.create_from_uri - wallets.py (wallet_create): Catch ValueError, TypeError, KeyFileError for keypair and wallet creation This change improves code quality by making exception handling more explicit and easier to debug while maintaining the same error recovery behavior.
Per reviewer feedback: bittensor_wallet.Keypair.create_from_uri() only raises TypeError, not ValueError. Removed ValueError from exception tuples on lines 380 and 431.
