Migrate actions toolset to modelcontextprotocol/go-sdk

[Copilot]

Closes: https://github.com/github/copilot-agent-services/issues/906
Related to #1428

Migrates the actions toolset (17 tools) from mark3labs/mcp-go to modelcontextprotocol/go-sdk.

Changes

Tool signatures

• Return type: (mcp.Tool, server.ToolHandlerFunc) → (mcp.Tool, mcp.ToolHandlerFor[map[string]any, any])
• Handler: func(ctx, request) (*Result, error) → func(ctx, *request, args) (*Result, any, error)

Schema definitions

• Converted DSL-based schemas to jsonschema.Schema structures
• Example: mcp.WithString("owner", mcp.Required()) → Properties: map[string]*jsonschema.Schema{"owner": {Type: "string"}}, Required: []string{"owner"}

Parameter extraction

• Updated to extract from args map[string]any instead of request.GetArguments()
• Changed RequiredParam[T](request, "key") → RequiredParam[T](args, "key")

Result helpers

• Replaced mcp.NewToolResultText/Error with utils.NewToolResultText/Error

Tests

• Updated all handler invocations to pass 3 arguments and handle 3 return values
• Added jsonschema import and type assertions for schema validation

All 17 tools migrated: ListWorkflows, ListWorkflowRuns, RunWorkflow, GetWorkflowRun, GetWorkflowRunLogs, ListWorkflowJobs, GetJobLogs, RerunWorkflowRun, RerunFailedJobs, CancelWorkflowRun, ListWorkflowRunArtifacts, DownloadWorkflowRunArtifact, DeleteWorkflowRunLogs, GetWorkflowRunUsage, plus 3 helper functions.

Pull Request Overview

This PR migrates the actions toolset (17 tools) from mark3labs/mcp-go to modelcontextprotocol/go-sdk, updating tool signatures, schema definitions, parameter extraction, and result helpers to match the new SDK patterns.

Key Changes:

• Updated all 17 action tools to use new SDK signatures: (mcp.Tool, mcp.ToolHandlerFor[map[string]any, any])
• Converted DSL-based schemas to jsonschema.Schema structures with explicit type definitions
• Migrated from request.GetArguments() to direct args map[string]any parameter extraction

There were no existing toolsnaps for actions tools before this migration. I've updated actions_test.go to generate new ones.

To ensure that tool schemas were not changed by the migration, I connected to the local (dev) server and remote servers and saved their tools/list responses in JSON files. I then compared the two files using a (copilot written) python script. The script checked for equivalence ignoring order of fields and ignoring omission of defaults (e.g. readOnlyHint FALSE is equivalent to being omitted).

To ensure the tools still worked, I reviewed the PR diffs, ran tests. I also asked copilot to test all 14 tools:
