test: stabilize platform vitest main checks

[ericksoa]

Summary

• scope the restricted dmesg CLI assertion to Linux, where NemoClaw actually calls dmesg
• make credential-back onboard scenarios select menu entries by visible label instead of platform-dependent numeric positions
• give the Ollama systemd loopback override test the shared provider-selection timeout

Validation

• npm run build:cli
• npx vitest run test/onboard-selection.test.ts --testTimeout 120000
• npx vitest run test/onboard-selection.test.ts -t "secret credential prompt" --testTimeout 120000
• npx vitest run test/onboard-selection.test.ts -t "applies the systemd loopback override" --testTimeout 120000
• npx vitest run src/lib/diagnostics/debug.test.ts --testTimeout 30000
• npx vitest run test/cli.test.ts -t "debug --quick explains restricted dmesg" --testTimeout 30000
• npx tsc -p tsconfig.src.json --noEmit
• git diff --check

Note: local pre-push full CLI coverage failed before push on unrelated local artifact setup (nemoclaw/dist/blueprint/private-networks.js and nemoclaw/node_modules/json5 missing), plus existing macOS-local CLI test noise. The targeted failures from Platform Vitest Main Watch are covered above.

Summary by CodeRabbit

Tests

• Improved test infrastructure for multi-step provider selection workflows with enhanced menu tracking and selection automation
• Made platform-specific tests conditionally skip on non-Linux systems

📝 Walkthrough

Walkthrough

The PR extends the credential-back test harness to support dynamic multi-step provider selection flows by introducing menu-aware prompt matching and state tracking, while also guarding a platform-specific CLI test to run only on Linux.

Changes

Multi-step Menu Selection in Credential-Back Tests

Layer / File(s)	Summary
Scenario type contract with menuSelections test/onboard-selection.test.ts	CredentialBackScenario gains optional menuSelections?: string[] field to configure dynamic menu option selection.
Subprocess initialization and output capture test/onboard-selection.test.ts	Subprocess script now initializes menuSelectionIndex, defines menuSelections from scenario, and introduces lines buffer to capture console output for menu matching.
Menu selection matching and prompt integration test/onboard-selection.test.ts	selectRecentMenuOption helper scans captured output for the most recent "Choose […]" menu entry matching a provided label, and integrates into credentials.prompt to handle "Choose" prompts when menuSelections are configured; falls back to answers otherwise. Redundant output buffer initialization is removed.
Subprocess result payloads with menuSelectionIndex test/onboard-selection.test.ts	Both subprocess success and exit result payloads now include menuSelectionIndex value alongside other captured data.
Parent test assertion and timeout constant test/onboard-selection.test.ts	Parent test asserts menuSelectionIndex matches scenario.menuSelections?.length, and systemd loopback override test switches to PROVIDER_SELECTION_TEST_TIMEOUT_MS constant instead of hardcoded 10_000.
Provider scenarios updated for menu selection test/onboard-selection.test.ts	Model Router, Hermes Provider Nous API Key, and Local NIM NGC API Key scenarios adjusted to use new menuSelections mechanism with simplified answers sequences for multi-step provider selection flows.

CLI Platform-Specific Test Guard

Layer / File(s)	Summary
Debug test Linux-only skip guard test/cli.test.ts	debug --quick "restricted dmesg" test wrapped in it.skipIf(os.platform() !== "linux") and description updated to include "on Linux".

Poem

🐰 With menus dancing through the test, we skip on platforms that need rest,
Each "Choose" now captured, matched with care—the subprocess flows without despair!
Menu selections traced and true, credentials prompt the way they should do. ✨
