* rewrite cache library as codeberg.org/gruf/go-structr, implement in gotosocial
* use actual go-structr release version (not just commit hash)
* revert go toolchain changes (damn you go for auto changing this)
* fix go mod woes
* ensure %w is used in calls to errs.Appendf()
* fix error checking
* fix possible panic
* remove unnecessary start/stop functions, move to main Cache{} struct, add note regarding which caches require start/stop
* fix copy-paste artifact... 😇
* fix all comment copy-paste artifacts
* remove dropID() function, now we can just use slices.DeleteFunc()
* use util.Deduplicate() instead of collate(), move collate to util
* move orderByIDs() to util package and "generify"
* add a util.DeleteIf() function, use this to delete entries on failed population
* use slices.DeleteFunc() instead of util.DeleteIf() (i had the logic mixed up in my head somehow lol)
* add note about how collate differs from deduplicate
