cat eb22a8bcc1 cmd/hakurei: move to cmd 
Having it at the project root never made sense since the "ego" name was deprecated. This change finally addresses it.

cat 1a8840bebc sandbox/seccomp: resolve rules natively 
This enables loading syscall filter policies from external cross-platform config files.

This also removes a significant amount of C code.

cat 31b7ddd122 fst: improve config 
The config struct more or less "grew" to what it is today. This change moves things around to make more sense and fixes nonsensical comments describing obsolete behaviour.

cat e9a7cd526f app: improve shim process management 
This ensures a signal gets delivered to the process instead of relying on parent death behaviour.

SIGCONT was chosen as it is the only signal an unprivileged process is allowed to send to processes with different credentials.

A custom signal handler is installed because the Go runtime does not expose signal information other than which signal was received, and shim must check pid to ensure reasonable behaviour.

cat a5d2f040fb cmd/fpkg/build: run final build step in nix 
This used to be a script that had to be run outside of nix because the sandbox disallows access to nix store state. Turns out closureInfo is the proper way to do that.

cat 124743ffd3 app: expose single run method 
App is no longer just a simple [exec.Cmd] wrapper, so exposing these steps separately no longer makes sense and actually hinders proper error handling, cleanup and cancellation. This change removes the five-second wait when the shim dies before receiving the payload, and provides caller the ability to gracefully stop execution of the confined process.
