BUG remove_seeds_from_memory(harm_categories=...) deletes seeds whose categories only contain the value as a substring

[u7k4rs6]

remove_seeds_from_memory(harm_categories=["hate"]) also deletes seeds tagged hate_speech, and even whatever. The list filters (harm_categories, authors, groups, parameters) go through field.contains(value), which is an unescaped LIKE '%value%' on the JSON text.

For get_seeds the substring match looks intentional (there are tests for it). But the remove methods already default value to an exact match so a short value can't wipe out more than you meant, and the list filters never got the same treatment.

seeds = [SeedPrompt(value="a", harm_categories=["hate"]),
         SeedPrompt(value="b", harm_categories=["hate_speech"]),
         SeedPrompt(value="c", harm_categories=["whatever"])]
await memory.add_seeds_to_memory_async(seeds=seeds, added_by="t")
memory.remove_seeds_from_memory(harm_categories=["hate"])  # removes all 3

Suggested fix: when exact=True (the default for removes), match whole list elements using the existing _get_condition_json_array_match helper, and leave get_seeds as is.
