Suggestion: Integrate example defaults directly into package/application

[aidankhogg]

Problem to solve

Type: Enhancement / Feature Request

Description:
Currently, the example defaults (e.g. YAML policies, detectors, transforms) exist as external examples. These should be more tightly integrated into the package/application itself.

Motivation:

• New users can run the package out-of-the-box without needing to fetch example files.
• Provides a clear, supported default baseline configuration.
• Reduces the gap between “hello world” usage and production deployment.

Proposal

• Ship a set of example defaults (policies, detectors, transforms) directly within the package.
• Make them accessible via redactable.get_default_policy() or similar helper.
• Ensure consistency between example docs and packaged defaults.
• Add tests to guarantee defaults always load and run correctly.

Additional context

Example usage:

from redactable import apply, get_default_policy

text = "card 4242 4242 4242 4242"
policy = get_default_policy()
print(apply(text, policy=policy))
