* feat: `vm.PrecompiledStatefulContract` can make `CALL`s
* fix: caller propagation
* feat: precompile can override default caller in `Call()`
* refactor: `WithUNSAFEForceDelegate()` replaces `WithCaller()`
* refactor: `WithUNSAFECallerAddressProxying()` instead of `ForceDelegate`
This matches the pattern used by `ava-labs/coreth` `NativeAssetCall`.
* refactor: `type callType` replaces `rwInheritance` + `delegation` types
* refactor: abstract return-data-proxy contract bytecode
* doc: fix comments from `46346f51`
* fix: `PrecompileEnvironment.Addresses()` for all call types
* chore: readability, linting & mark upstream test flaky
* test: `PrecompileEnvironment.Call()`
* refactor: improved {read,maintain}ability
* doc: fix `evmCallArgs` example
* test: `PrecompileEnvironment.Call()` input data
* fix: write protection for non-zero call value
