Logs not being pruned when setting receipts_log_filter

[spalladino]

Hey folks, I got a question about receipts_log_filter pruning. I've set up a node using this config to keep only receipts (and by extension getLogs IIUC) from specific contracts, but I see that all logs are being persisted instead.

I set out Claude to review why the pruning wasn't working, and he identified what may be a bug (or design decision) in the mode returned by the Segment impl in ReceiptsByLogs.

Is it expected that the pruner does not remove old logs via receipts_log_filter? Or is it a bug? FWIW here's Claude's assessment: https://gist.github.com/spalladino/f6dcb866031bd4e96bff70fce0c31b47
