📝 Walkthrough

Walkthrough

Prints step-by-step Discord webhook and Email SMTP guides to the console before prompting for credentials in kdm config setup; tests were extended to assert the guide messages and their ordering relative to the first interactive prompt.

Changes

Setup Guides for Service Configuration

Layer / File(s)	Summary
Guide helper functions and flow integration src/commands/config.ts	Two new non-exported helpers (printDiscordWebhookGuide, printEmailSmtpGuide) output formatted setup instructions. The config setup action calls the appropriate guide immediately after service selection and before credential prompts; the prior single-line SMTP password warning was removed.
Test helpers and assertions src/__tests__/config.test.ts	Adds local test helpers to capture console.log and tui.input invocation order. Discord and Email setup tests now assert presence of additional guide messages (Discord: webhook setup and Integrations > Webhooks; Email: SMTP setup and KDM_SMTP_PASSWORD) and verify the guide logs occur before the first prompt.

- Around line 65-66: Update config.test.ts to assert ordering and add validation
edge-case tests: locate the tests that use consoleLogSpy (the expectations with
expect.stringMatching(/Discord webhook setup/i) and
expect.stringContaining('Integrations > Webhooks')) and replace/add assertions
that verify the guide log appears before the first credential prompt by
comparing indices in consoleLogSpy.mock.calls (e.g., find call index for the
guide message and the credential prompt message and assert guideIndex <
promptIndex). Also add separate tests exercising invalid Discord URL and missing
SMTP host paths (call the same setup/config loader used in these tests) and
assert they produce the expected validation error logs/messages or throw/exit
behavior (matching the project's existing error handling), using spies on
console.error or the process-exit behavior used elsewhere in the suite.
