Inconsistent behavior with `cursor` function syntax

Description:

I encountered an issue with the cursor function where two syntactically similar usages produce different results. The first usage works as expected, while the second one does not.

Working Code:

cursor((state) => state.manualCursor, { defaultValue: (state) => state.lastRunDateTime || 'now' })

// Lazy load equivalent 
cursor($.manualCursor, { defaultValue: $.lastRunDateTime || 'now' });

Steps to Reproduce:

1. Run the job with working code with initial state as {}. It will print in CLI logs Setting cursor "now" to: HH:mm D M YYY
2. Run the job with non-working code with initial state as {}. It will print in CLI logs Setting cursor "now" to: undefined

Start by locating the cursor function and comparing the two JavaScript call forms shown in the issue. Reproduce both with initial state {} using the CLI and the listed versions; done means equivalent forms resolve the cursor consistently instead of producing undefined.
