🛡️ Sentinel: Fix EOL detection for older and odd Node.js versions

[google-labs-jules]

This PR updates the End-of-Life (EOL) detection logic in src/index.ts to accurately identify older and odd-numbered Node.js versions as EOL.

Previously, checkEOL only returned true if the major version existed in the EOL_DATES map and the current date was past the EOL date. The map only contained recent even-numbered LTS versions (18, 20, 22, 24). This meant that:

• Very old versions (e.g., Node 10, 8) were considered "supported" (false negative).
• Recently EOL'd versions (Node 12, 14, 16) were considered "supported" (false negative).
• Odd-numbered versions (e.g., 19, 21) were considered "supported" (false negative).

The fix:

1. Adds a hard check for major < 12 to instantly flag ancient versions as EOL.
2. Updates EOL_DATES to include dates for Node 12, 14, 16, 18, 20, 22, 24, and odd versions 19, 21, 23, 25.

This ensures that security tools and consumers relying on isEOL get accurate information about the security status of the Node.js runtime.

Summary by cubic

Fix EOL detection so older and odd-numbered Node.js versions are correctly flagged as End-of-Life. This removes false “supported” results and ensures accurate security status for isEOL consumers.

• Bug Fixes
  • Added EOL dates for 12, 14, 16 and odd 19, 21, 23, 25 (alongside 18, 20, 22, 24).
  • Mark any major < 12 as EOL.
  • If no date is known and major ≥ 12, default to not EOL (to allow future versions).
