Why This Matters

integration_health.py is now a long mixed file containing provider validators, raw HTTP probes, and client-backed checks.

Read First

• app/cli/wizard/integration_health.py
• tests/cli/wizard/test_integration_health.py

Scope

1. Move validator functions into smaller modules grouped by style, for example client_validators.py, http_probe_validators.py, and mcp_validators.py.
2. Keep app/cli/wizard/integration_health.py as the stable import surface by re-exporting the same public functions.
3. Do not change the return strings more than necessary in the same PR.

Tests / Coverage

• split the existing test module only if it becomes easier to read
• keep import paths stable in tests while you move the implementations
• add at least one test that imports through the old public module path

Acceptance Criteria

• the file is broken into smaller modules
• public imports from app.cli.wizard.integration_health still work
• existing validator behavior stays the same
