Allow user-scoped hooks

[david-mears-2]

Describe the feature or problem you'd like to solve

At the moment, all hooks are repo-scoped. I want to have a hook that will be invoked regardless of which repo I am working in.

Proposed solution

Like .agents/skills for user-scoped skills, use .agents/hooks for user-scoped hooks.

Example prompts or workflows

This is an example of a hook I'd like to have user-scoped: https://github.com/github/awesome-copilot/blob/main/hooks/tool-guardian/README.md

This was addressed in v0.0.422. You can place hook JSON files in ~/.copilot/hooks/ and they will apply across all repos without needing per-repo configuration. The exact path differs from the .agents/hooks location suggested here, but the user-scoped hook behavior is available. v1.0.8 also added the ability to define hooks in config files as another user-scoped option. If you believe this isn't resolved, please feel free to reopen this issue.
