Updates rusty_alloc from 2.2.0 to 2.2.1

Release notes

Sourced from rusty_alloc's releases.

rusty_alloc-api-v2.2.1

Performance

• GlobalAlloc methods are #[inline], as the mimalloc crate's are, so rustc's __rust_alloc / __rust_dealloc shims carry the fast path instead of jumping to it, and dealloc is the free fast path with its null test folded away. Measured whole-program against 2.2.0 on two deterministic Rust workloads (bench/rust-globalalloc.sh): -21.1 % and -5.8 %.
• Layouts aligned up to two words (16 bytes on 64-bit) come from the natural size classes, which are already aligned that far, instead of the aligned path; every hashbrown table is such a layout. tests/natural_align.rs pins the alignment for every size class through alloc, alloc_zeroed and realloc.
• realloc keeps a block in place at any alignment when it fits instead of always allocating, copying and freeing above 8 bytes of alignment: -27.3 % on an over-aligned buffer workload.

rusty_alloc-v2.2.1

Fixed

• Growing a huge block with realloc copied its whole reservation. A huge segment's page reported its usable size as the chunk-rounded reservation minus the header — 64 MiB for a 33 MB request, 96 MiB for a 64 MB one — and realloc copies usable_size bytes when it moves a block, so growing a 33 MB block copied, and first-touched on both sides, twice what the caller had written; zalloc on a recycled chunk zeroed the same extent. A consumer measured the two realloc steps that cross the segment size at 1.41x and 1.23x mimalloc, 0/6 pairs, with every step below it faster than mimalloc, and a Vec pushed to 64 MB at 1.23x (docs/plans/youslowbro.md §3). The page now reports the request rounded up to a slice — upstream's psize, and what mi_usable_size returns there — while the reservation itself is unchanged. On the consumer's own harness, pinned and ABBA-paired against the tree before the fix: see the LEDGER entry for the numbers. tests/alloc_core.rs::huge_usable_size_is_the_request_not_the_reservation pins the reported size and the bytes a move preserves.
• The options pass made 251 allocations through the global allocator on the first allocation of every process. options::ensure_init built its 38 x 2 environment keys with to_uppercase and format! and read them with std::env::var, every one an owned String — inside the heap that was still being set up, and on every short CLI run. mimalloc makes none. The keys are now built in a stack buffer sized by the table and read through prim::getenv (a raw getenv / GetEnvironmentVariableA, the calls upstream's prim makes) into a second stack buffer, and the value grammar is parsed in place. On the consumer's counting probe the process's start-up went from 263 allocations to 12, which is exactly what mimalloc reads there. tests/options_env.rs proves the variables still arrive (both prefixes, precedence, the boolean grammar, KiB scaling) from a child process, and rusty_alloc_api/tests/reentrancy.rs fails the build if the allocator ever allocates through the global allocator again while serving a request (docs/plans/youslowbro.md §4).
