Bump MSRV to 1.86 (and codspeed) (#149)

Since we're on the 2024 edition, bumping the msrv is no longer
considered a breaking change because of
[this](https://doc.rust-lang.org/edition-guide/rust-2024/cargo-resolver.html)
change. 81% of crates.io traffic comes from 1.86 or later, compared to
89% that use 1.85 or later, so we don't lose a huge amount the potential
ecosystem.
This also unblocks codspeed with much better capabilities at "seeing"
inlined code, which is very valuable here.
