sccache 0.18.0

Summary
sccache 0.18.0 is a broad correctness and coverage release: a lot of compiler flags that used to
force a cache miss are now understood, several cache-key and multi-level storage bugs are fixed,
and the Azure backend gained passwordless authentication.
Highlights:
- Cache-key correctness: the assembler gcc/clang would actually invoke is now part of the cache
key, so two toolchains with different binutils can no longer hand each other the wrong object
file (#2843). SCCACHE_BASEDIRS now also strips base directories from the compiler arguments,
so flags like -ffile-prefix-map=/home/user/project=. stop tying an entry to one checkout
(#2840).
- MSVC/clang flag coverage: support for /openmp:llvm, the /fsanitize*, /fsanitize-coverage*
and /fno-sanitize* families, /feature, arm64EC and fastfail, /d20bforceinline, and a large
batch of other flags (#2807, #2830, #2831, #2832), plus more clang CLI options (#2834). gcc now
marks flags as TooHard when they would require caching something else (#2833).
- CUDA: nvcc dryrun parsing works with CUDA 13.3 (#2722), escaped quotes in Windows dryrun
lines are protected before backslash flattening (#2811), and the
--diag-error/--diag-suppress/--diag-warn family is accepted (#2816).
- Multi-level cache: a chain with any writable level is writable again — a single read-only
level no longer makes the whole storage read-only (#2778) — and reads are no longer issued twice
(#2835).
- Azure: Microsoft Entra ID (passwordless) authentication for the Azure Blob backend, for
storage accounts that disable shared-key access (#2802).
- Distributed compilation: rlibs are no longer trimmed from crates that also emit a cdylib,
which made those jobs fail on the build server (#2839).
- Process handling: the jobserver is no longer handed to children that can't use it, which
restores the posix_spawn fast path for child spawns (#2827), and daemonization now uses an
allow-list for inherited file descriptors, fixing make deadlocks caused by leaked jobserver FDs
(#2841).
- MSRV is now 1.91.0 (#2793).
