Make git hooks a noop if entire is not enabled in the repo

[Soph]

In the case of git hooks being installed but entire not enabled in the repository this will make any git hook call a noop.

#460

PR Summary

Low Risk
Behavior is narrowly scoped to hook execution gating and adds test coverage; primary risk is unintentionally skipping hooks if settings detection fails (e.g., path resolution/load errors).

Overview
Git hook commands are now no-ops when Entire is not configured for the current repo or has been disabled, preventing globally-installed hooks from creating .entire artifacts or running strategy handlers.

This adds settings.IsSetUp() / settings.IsSetUpAndEnabled() and uses them in hooks_git_cmd.go to skip initHookLogging() (defense-in-depth) and to gate each hook subcommand via a gitHooksDisabled flag. Tests were updated to create settings.json where required and new cases assert logging does not create .entire/logs when not set up or when enabled:false.

Pull request overview

This PR addresses issue #460 by making git hooks no-ops when Entire is not enabled in a repository. The fix prevents global git hooks from creating .entire/logs/ directories in repos where Entire has never been set up or has been disabled.

Changes:

• Added IsSetUp() and IsSetUpAndEnabled() helper functions to check if Entire is active in a repo
• Updated git hook commands to check if Entire is enabled before performing any operations
• Added comprehensive tests for the new behavior (skipping when not set up or disabled)
