📝 Walkthrough

Walkthrough

The code now uses borrow_and_update() instead of borrows() to obtain current progress values in the progress monitoring path, affecting both initial dispatch and subsequent updates. This ensures the latest progress state is captured before cloning and sending to callbacks.

Changes

Cohort / File(s)	Summary
Progress Monitoring Path dash-spv-ffi/src/client.rs	Replaced borrows() calls with borrow_and_update() to ensure latest progress state is obtained before dispatching to callback in progress monitoring flow.

Poem

🐰 A rabbit hops through progress states so fine,
Updating borrows to keep timing in line,
Two little changes, precise and divine,
Now callbacks receive the freshest design! ✨

Title check	⚠️ Warning	The PR title references 'cooldown' and 'wait for updates' but the raw summary only describes a change from borrows to borrow_and_update() to ensure latest progress state before cloning, with no mention of cooldown logic or event dispatch prevention.	Align the title with the actual changes described: the modification to use borrow_and_update() for obtaining current progress values, not cooldown-based event dispatch.
