4c23290c29 Fix MCP unit tests to use correct /tools/call endpoint
- Update all Hub tool tests to use POST /tools/call endpoint instead
  of individual paths like /workloads, /calls, /stats
- Verify arguments in POST body instead of URL query parameters
- Add newMockHubHandler helper for proper Hub endpoint mocking
- Split TestMCP_ToolsList into three tests:
  - TestMCP_ToolsList_CLIOnly: Tests without Hub backend
  - TestMCP_ToolsList_WithDestructive: Tests with destructive flag
  - TestMCP_ToolsList_WithHubBackend: Tests with mock Hub providing tools
- Fix TestMCP_FullConversation to mock Hub MCP endpoint correctly
- Rename URL encoding tests for clarity
- All tests now correctly reflect the implementation

b774d333e9 Add MCP server unit tests
Comprehensive unit tests for the MCP server implementation:
- Protocol tests (initialize, tools/list, tools/call, prompts/list, prompts/get)
- Tool tests (check_kubeshark_status, start_kubeshark, stop_kubeshark)
- Hub integration tests (tool fetching, caching, prompt handling)
- Error handling tests
- Edge case tests

1471cb2365 Fix lint errors in mcpRunner.go
- Use type conversion instead of struct literals for hubMCPTool -> mcpTool
  and hubMCPPromptArg -> mcpPromptArg (S1016 gosimple)
- Lowercase error string to follow Go conventions (ST1005 staticcheck)

9a6c81620a Address code review comments for MCP implementation
- Add 30s timeout to HTTP client to prevent hanging requests
- Add scanner.Err() check after stdin processing loop
- Close HTTP response bodies to prevent resource leaks
- Add goroutine to wait on started process to prevent zombies
- Simplify polling loop by removing ineffective context check
- Advertise check_kubeshark_status in URL mode (was callable but hidden)
- Update documentation to clarify URL mode only disables start/stop

6d46d38701 Add MCP (Model Context Protocol) server command
Implement `kubeshark mcp` command that runs an MCP server over stdio,
enabling AI assistants to query Kubeshark's network visibility data.

Features:
- MCP protocol implementation (JSON-RPC 2.0 over stdio)
- Dynamic tool discovery from Hub's /api/mcp endpoint
- Local cluster management tools (check_kubeshark_status, start_kubeshark, stop_kubeshark)
- --url flag for direct connection to existing Kubeshark deployment
- --kubeconfig flag for proxy mode with kubectl
- --allow-destructive flag to enable start/stop operations (safe by default)
- --list-tools flag to display available tools
- --mcp-config flag to generate MCP client configuration
- 5-minute cache TTL for Hub tools/prompts
- Prompts for common analysis tasks
