Add Prefix-Based Iteration Stopping to Cache

What changed?

Added new prefix parameter to iteration methods in Cache class. This parameter makes iteration stop when key no longer starts with prefix.

Methods changed:

• items()
• keys()
• values()
• columns()
• entities()

How to use:

cache['user:1'] = 'alice'
cache['user:2'] = 'bob'
cache['order:1'] = 'order1'

# Get only keys that start with 'user:'
list(cache.keys(prefix='user:'))  # ['user:1', 'user:2']

# Get only keys that start with 'order:'
list(cache.keys(prefix='order:'))  # ['order:1']

Tests

Added 8 new tests for prefix functionality. All 21 cache tests pass.

Breaking change?

No. Old code works same way. New parameter is optional and default is None.
