feat: add net10 support while retaining net9 and net8 compatibility (#995)

what changed
- added `net10` target to project multi-targeting and adjusted
conditional compilation where necessary
- updated ci/workflow to build and test for `net10`, `net9`, and `net8`
- preserved runtime behaviour and public apis for `net9` and `net8`
- applied minor fixes and conditional code paths to address api
differences introduced in `net10`

compatibility & migration notes
- multi-targeting preserves compatibility across `net8`, `net9`, and
`net10`
- no breaking api changes introduced by this pr
- consumers targeting older frameworks should require no changes
- if consumers rely on framework-specific behaviour, validate in your
environment using `net10`
