feat(perf) Add continuous profiling support

[Sobeston]

Pretty easy change, should be handy.

Has a good amount of detail, even in ReleaseSafe (thanks @Rexicon226 for suggesting to disable omit_frame_pointer).

If you're using docker desktop + macos, this won't work - the profiler won't be able to find your host's process.

(focused in on the gossip verification)

(focused further, into bincode)

Wow, nice! How can I test this out?

Start Sig, e.g.
./zig-out/bin/sig gossip -n testnet 2>&1 | tee -a logs/sig.log
then should be as simple as
[metrics]$ SIG_PID=$(pgrep sig) docker compose up

(I'm not sure how common pgrep is, but there's 1000 ways to do that)

Edit: oh and open Grafana, find the Pyroscope data source, group by service_name, look for "sig".
