Release 1.4.1: search discovery foundation

[umudhasanli]

Summary

• add four original, indexable developer guides for JavaScript PII redaction, Node.js log secrets, LLM prompt privacy, and scoped MCP tool restoration
• turn the docs site into a crawlable content cluster with a guide hub, internal navigation, canonical URLs, social metadata, structured data, and complete sitemap coverage
• refresh the landing page for 1.4.1 and point package/repository discovery toward the live docs site
• add automated checks for metadata uniqueness, JSON-LD validity, local-link integrity, sitemap coverage, and release-label freshness

Why

The existing site had one HTML page, so search engines had no focused result for the concrete problems the package solves. These pages answer distinct developer intents with tested code and explicit security boundaries rather than keyword-only landing pages.

Verification

• npm test — 198 tests passed
• npm audit — 0 vulnerabilities
• npm pack --dry-run — expected 1.4.1 package contents
• OpenAI privacy, Express/Pino, and universal-boundaries examples passed
• XML sitemap and every internal docs link validated
