Add GitHub Actions MCP server for viewing workflow results (#231)

* actions server

* tmp

* Replace view_actions_results with additional_permissions input

- Changed input from boolean view_actions_results to a more flexible additional_permissions format
- Uses newline-separated colon format similar to claude_env (e.g., "actions: read")
- Maintains permission checking to warn users when their token lacks required permissions
- Updated all tests to use the new format

This allows for future extensibility while currently supporting only "actions: read" permission.

* Update GitHub Actions MCP server with RUNNER_TEMP and status filtering

- Use RUNNER_TEMP environment variable for log storage directory (defaults to /tmp)
- Add status parameter to get_ci_status tool to filter workflow runs
- Supported statuses: completed, action_required, cancelled, failure, neutral, skipped, stale, success, timed_out, in_progress, queued, requested, waiting, pending
- Pass RUNNER_TEMP from install-mcp-server.ts to the MCP server environment

* Add GitHub Actions MCP tools to allowed tools when actions:read is granted

- Automatically include github_ci MCP server tools in allowed tools list when actions:read permission is granted
- Added mcp__github_ci__get_ci_status, mcp__github_ci__get_workflow_run_details, mcp__github_ci__download_job_log
- Simplified permission checking to avoid duplicate parsing logic
- Added tests for the new functionality

This ensures Claude can use the Actions tools when the server is enabled.

* Refactor additional permissions parsing to parseGitHubContext

- Moved additional permissions parsing from individual functions to centralized parseGitHubContext
- Added parseAdditionalPermissions function to handle newline-separated colon format
- Removed redundant additionalPermissions parameter from prepareMcpConfig
- Updated tests to use permissions from context instead of passing as parameter
- Added comprehensive tests for parseAdditionalPermissions function

This centralizes all input parsing logic in one place for better maintainability.

* Remove unnecessary hasActionsReadPermission parameter from createPrompt

- Removed hasActionsReadPermission parameter since createPrompt has access to context
- Calculate hasActionsReadPermission directly from context.inputs.additionalPermissions inside createPrompt
- Simplified prepare.ts by removing intermediate permission check

This completes the refactoring to centralize all permission handling through the context object.

* docs: Add documentation for additional_permissions feature

- Document the new additional_permissions input that replaces view_actions_results
- Add dedicated section explaining CI/CD integration with actions:read permission
- Include example workflow showing how to grant GitHub token permissions
- Update main workflow example to show optional additional_permissions usage
