cache iteration: various fixes- will invalidate exisiting cache

[dmadisetti]

This has fixes for:

• Shadowed arguments
• Formatting causing issues with context block: Issue with formating and persistent caching #2633
• improved df "object detection": Persistent cache with a polars dataframe #2661

Following PR changes:

• Detect when execution hash relies on a another hash object (cache breaking) (Caching robustness and determinism #3270)
• Allow for pickle hash as fallback for "unhashable" variables (Caching robustness and determinism #3270)
• Expand @persistent_cache api (this shouldn't cache bust, so I might just follow up) (Cache interface options #2653)

Nice!

Expand @persistent_cache api (this shouldn't cache bust, so I might just follow up) (#2653)

This should be its own PR, with perhaps some API discussion up front first.

Detect when execution hash relies on a another hash object (cache breaking) (#3270)
Allow for pickle hash as fallback for "unhashable" variables (#3270)

May as well include in a separate PR?

@dmadisetti I know this is marked as a draft, but just double checking — let us know if and when you want a review.

Breaking up the PRs, I think this is fine to be reviewed and merge. Sorry it's a little messy- rebased from some old branches.

I'll try to get the other hash breaking change in before next release so these can go out together

Nice fixes! Just a few small comments
