Split CLI lib.rs into modules

[john-h-kastner-aws]

Description of changes

Sorry for the large diff, but this has been bothering me for a while. I hope you can trust that I haven't changed any of the code.

I want to do something similar for api.rs in cedar-policy, but that's a larger project.

Issue #, if available

Checklist for requesting a review

The change in this PR is (choose one, and delete the other options):

• A breaking change requiring a major version bump to cedar-policy (e.g., changes to the signature of an existing API).
• A backwards-compatible change requiring a minor version bump to cedar-policy (e.g., addition of a new API).
• A bug fix or other functionality change requiring a patch to cedar-policy.
• A change "invisible" to users (e.g., documentation, changes to "internal" crates like cedar-policy-core, cedar-validator, etc.)
• A change (breaking or otherwise) that only impacts unreleased or experimental code.

I confirm that this PR (choose one, and delete the other options):

• Updates the "Unreleased" section of the CHANGELOG with a description of my change (required for major/minor version bumps).
• Does not update the CHANGELOG because my change does not significantly impact released code.

I confirm that cedar-spec (choose one, and delete the other options):

• Does not require updates because my change does not impact the Cedar formal model or DRT infrastructure.
• Requires updates, and I have made / will make these updates myself. (Please include in your description a timeline or link to the relevant PR in cedar-spec, and how you have tested that your updates are correct.)
• Requires updates, but I do not plan to make them in the near future. (Make sure that your changes are hidden behind a feature flag to mark them as experimental.)
• I'm not sure how my change impacts cedar-spec. (Post your PR anyways, and we'll discuss in the comments.)

I confirm that docs.cedarpolicy.com (choose one, and delete the other options):

• Does not require updates because my change does not impact the Cedar language specification.
• Requires updates, and I have made / will make these updates myself. (Please include in your description a timeline or link to the relevant PR in cedar-docs. PRs should be targeted at a staging-X.Y branch, not main.)
• I'm not sure how my change impacts the documentation. (Post your PR anyways, and we'll discuss in the comments.)

Pull request overview

This PR refactors the Cedar CLI's lib.rs by splitting it into well-organized modules. The large monolithic library file is being restructured into a hierarchical module system with:

• A command/ module containing individual files for each CLI subcommand
• A utils/ module containing shared utility functions for reading schemas, policies, requests, and entities

Changes:

• Split lib.rs into modular structure with command.rs and utils.rs as the main module hubs
• Created 19 new command-specific files in cedar-policy-cli/src/command/ directory for each subcommand
• Created 5 new utility files in cedar-policy-cli/src/utils/ directory for shared functionality
• Maintained all existing functionality without code logic changes; this is purely organizational
