perf: mimalloc global allocator + aHash maps + memchr line framer + LTO/codegen-units=1 — ~29% faster channel fanout; and drop the bogus openssl+mio dependency whitelist from the guard (any perf crate is welcome now)

# native-rust-guard — echoIRCd's standing invariant.
#
# echoIRCd is ORIGINAL Rust — no code copied or translated from any other project.
# Every module, command and core function is written natively in Rust. This guard
# fails if that slips. Run it any time: bash scripts/native-rust-guard.sh
# It is also wired into an editor hook so it runs automatically on edits.
# Every module, command and core function is written natively in Rust, and our own
# crate stays `#![forbid(unsafe_code)]`. This guard fails if that slips. Run it any
# time: bash scripts/native-rust-guard.sh (also wired into an editor hook).
#
# NOTE: there is NO dependency whitelist. Any crate that makes the daemon faster or
# better is welcome (ahash, mimalloc, memchr, rustls, tokio, …); crates keep their
# own `unsafe` internal, which our forbid(unsafe_code) does not (and cannot) police.
