feat(devin-lang): add support for agent properties #101

The DevInLexer and DevInParser have been updated to support agent properties, which are specified using a colon (:) followed by a property value. This change also updates the grammar to support the new syntax and adds new tokens for COLON and PROPERTY_VALUE.
