feat: move copilot tools to default copilot toolset (#2039)

* feat: move copilot tools to default copilot toolset

Move AssignCopilotToIssue and RequestCopilotReview from the issues and
pull_requests toolsets respectively into a new default-enabled copilot
toolset. This groups all copilot-related tools together and makes them
available by default.

- Set Default: true on ToolsetMetadataCopilot
- Remove copilot from RemoteOnlyToolsets()
- Update AllTools() grouping and tests
- Regenerate docs

* refactor: move copilot tools to dedicated copilot.go

Extract AssignCopilotToIssue, RequestCopilotReview, AssignCodingAgentPrompt,
and all supporting types/helpers from issues.go and pullrequests.go into
copilot.go and copilot_test.go.

This follows the existing convention where each domain (actions, dependabot,
discussions, gists, etc.) has its own file, and keeps the copilot toolset
implementation cohesive in one place.
