docs: update Discord invite link across docs

[dragnot]

Summary

Update the remaining Discord invite links across the docs to the current invite https://discord.com/invite/Y2mMT9VdMy.

Changes

• Replace https://discord.gg/6M4QwDXn2w with https://discord.com/invite/Y2mMT9VdMy in:
  • README.md (badge link + Community section)
  • index.md (badge link)
  • References/index.md (2 references)
  • _includes/head_custom.html
  • llms.txt
• The shields.io member-count badge (Discord server ID 1146782921294884966) is intentionally left unchanged, since it is a server identifier, not an invite link.

Testing

Docs-only change. Verified no 6M4QwDXn2w references remain and all invite links now point to the new URL.

Memory / Performance Impact

N/A (docs-only).
