* Anki: Replace lazy_static with once_cell Unify to once_cell, lazy_static's replacement. The latter in unmaintained. * Anki: Replace once_cell with stabilized LazyCell / LazyLock as far as possible Since 1.80: https://github.com/rust-lang/rust/issues/109736 and https://github.com/rust-lang/rust/pull/98165 Non-Thread-Safe Lazy → std::cell::LazyCell https://doc.rust-lang.org/nightly/std/cell/struct.LazyCell.html Thread-safe SyncLazy → std::sync::LazyLock https://doc.rust-lang.org/nightly/std/sync/struct.LazyLock.html The compiler accepted LazyCell only in minilints. The final use in rslib/src/log.rs couldn't be replaced since get_or_try_init has not yet been standardized: https://github.com/rust-lang/rust/issues/109737 * Declare correct MSRV (dae) Some of our deps require newer Rust versions, so this was misleading. Updating the MSRV also allows us to use .inspect() on Option now
