test(0145): unit + integration + launcher + claudecode coverage

cmd/devicemesh-mcp/main_test.go (10 tests): - TestInitialize: JSON-RPC initialize frame → serverInfo + capabilities. - TestToolsList: tools/list → 16 user-mode entries, cada uno con name + inputSchema valido. - TestToolsCallExec: tools/call name=exec → mock device-agent (httptest) recibe capability=shell.exec, MCP response content contiene "hi". - TestToolsCallInvalidTool: name desconocido → isError o error envelope. - TestNotificationsInitializedNoResponse: notification (sin id) → cero responses. - TestUserModeFiltersPkgInstall: --mode user oculta pkg.install, --mode sudo la expone. - TestToolsAllowedNarrows: --tools-allowed exec,fs.read → solo 2. - TestSplitCSV, TestParseMode, TestIsCleanShutdown: helpers. cmd/devicemesh-mcp/integration_test.go: - TestIntegrationBinarySubprocess: build el binario en tmp + spawn como child via exec.Command + pipe real + secuencia initialize -> notifications/initialized -> tools/list -> tools/call. Valida el path identico al que usara claude. devagents/mcp_bridge_test.go (9 tests): - Disabled paths (nil DM, ExposeViaMCP=false, provider!=claude-code). - Applied path: /tmp/<agent>-mcp-config.json JSON valido, mode 0600, mcpServers.devicemesh con command apuntando al binario fake. - AllowedTools formato mcp__<server>__<tool>. - DisableTools=true overrideado a false. - URLEnv override gana sobre YAML. - Binary missing → ok=false sin panico. - BuildClaudeAllowedToolNames default server name. - ResolveBridgedToolNames respeta mode + ToolsAllowed. - ShouldExposeViaMCP cubre nil/disabled/default/explicit-true/false. shell/llm/claudecode_test.go: - TestBuildClaudeArgs_DisableTools actualizado: solo emite --tools "" cuando AllowedTools ESTA vacio. La regla nueva (issue 0145) da precedencia a AllowedTools. - Anadido TestBuildClaudeArgs_DisableToolsButAllowedToolsWins. - Anadido TestBuildClaudeArgs_MCPConfigPath. bridge.go fix: cambio NewTool + WithRawInputSchema a NewToolWithRawSchema porque NewTool inicializa ToolInputSchema.Type="object" por default, lo cual entra en conflicto con RawInputSchema en MarshalJSON del SDK. Suite completa pasa con -tags goolm -count=1. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
