Show specific error messages for Slack auth extraction failures

[devxoul]

Summary

• Replace the generic "Extracted tokens are invalid" message with cause-specific errors so users can self-diagnose. Tracks SlackError.code from each failed workspace validation and maps it to an actionable message.

Changes

src/platforms/slack/commands/auth.ts

• Collect SlackError.code from each failed workspace validation.
• Add getExtractionErrorMessage() that maps failure codes to specific messages:
  • missing_cookie → "Cookie extraction failed. Make sure the Slack desktop app is installed and grant Keychain access when prompted."
  • invalid_auth → "Slack session has expired. Sign into the Slack desktop app, wait a few seconds, then re-run this command."
  • Default → original generic message (fallback).
• Add hint field suggesting --debug when not already enabled.

src/platforms/slack/commands/auth.test.ts

• Add 5 tests for getExtractionErrorMessage() covering each code, priority order, and edge cases.

Verified

• bun test — 28 pass, 0 fail.
• bun typecheck — clean.
• bun lint — clean.
