chore(message-parser): add test coverage for isNodeOfType guard

[Harshith1702]

guards.ts had 60% statement coverage and 0% branch coverage.

This PR adds a dedicated test suite covering all branches of isNodeOfType:

• matching type returns true
• null returns false
• non-object returns false
• mismatched type returns false
• missing type property returns false
• undefined returns false

All 594 tests pass.
