Fix link check CI configuration error and broken documentation links

[Copilot]

Link check CI was failing due to two issues: invalid configuration in lychee.toml and broken links in the documentation.

Changes

• lychee.toml: Changed verbose = true to verbose = "info" (lychee v0.21.0 expects a string log level)
• .gitignore: Added .lycheecache to exclude lychee's cache directory
• Documentation links: Fixed 7 broken links found by the link checker:
  • Replaced 6 GitHub Discussions links with GitHub Issues (discussions not enabled for this repository)
  • Replaced 1 non-existent examples/task-manager reference with examples/todo

Configuration Fix

# Before
verbose = true

# After
# Accepts log level: "error", "warn", "info", "debug", "trace"
verbose = "info"

Broken Links Fixed

Files updated:

• content/blog/metadata-driven-architecture.mdx
• content/blog/protocol-first-development.mdx
• content/docs/specifications/index.mdx
• content/docs/tutorials.mdx
• content/docs/troubleshooting.mdx
• content/docs/faq.mdx
• content/docs/quick-start/build-first-app.mdx

All links now validate successfully with lychee v0.21.0.

Fixed! The link check was failing due to 7 broken links in the documentation. All issues have been resolved in commit 8c9bfaa:

Fixed links:

• 6 GitHub Discussions links → replaced with GitHub Issues (discussions not enabled for this repo)
• 1 non-existent examples/task-manager → replaced with examples/todo

All links now validate successfully. The CI should pass on the next run.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
