CI hardening: arm/mingw matrix, nightly deep-fuzz + soak, sodium watch, implementers notes#151

… implementers notes
Process improvements, no library code change:
- ci.yml: add ubuntu-24.04-arm to the build/test matrix and a MinGW
(msys2 gcc + ninja) leg, so the __MINGW32__ code path and arm64 are
covered on every push. Smoke fuzz now warm-starts from the checked-in
seed corpus.
- scheduled.yml (new, nightly + manual dispatch):
- deep-fuzz: 20 min per target with an accumulating corpus cached
across runs via actions/cache.
- soak: 15 min ASan soak; clean timeout is success, any abort fails.
- sodium-upstream-check: compares SODIUM_VERSION_STRING to the latest
jedisct1/libsodium release and opens a tracking issue if behind.
- fuzz/corpus/fuzz_parse_address: hand-written, verified-clean seed
corpus of valid/edge address strings for a warm fuzzer start.
- sodium/NOTES.md: document the upstream tracking process the scheduled
check drives.
- IMPLEMENTERS.md (new): portable writeup of the replay-protection
integer overflow and the STANDARD.md errata, for maintainers of the
C#, Go, Rust, and TypeScript ports to check their implementations
against. Linked from README.
- CLAUDE.md: reflect the expanded CI, nightly jobs, and that OSS-Fuzz
enrollment is the one remaining external process step.

Summary
Process improvements only — no library code change. Closes the last "Process gaps" items from CLAUDE.md.
Improvement 4 — matrix (verified by this PR's CI):
ubuntu-24.04-armto the build/test matrix (Debug + Release).__MINGW32__code path — packet-tagging disabled, QOS typedefs — is actually compiled and tested on every push.Improvement 2 — continuous-ish fuzzing:
scheduled.ymldeep-fuzzjob: 20 min per target nightly, with an accumulating corpus cached across runs viaactions/cache(the correct pattern for coverage that grows over time).fuzz/corpus/fuzz_parse_address/: hand-written, ASan-verified seed set of valid/edge address strings.Improvement 3 — nightly soak:
scheduled.ymlsoakjob: 15-minute ASan soak; a clean timeout is success, any abort (assert or sanitizer) fails the job.Improvement 5 — sodium upstream tracking:
scheduled.ymlsodium-upstream-checkjob comparesSODIUM_VERSION_STRING(1.0.20) to the latestjedisct1/libsodiumrelease and opens a tracking issue if behind (dedup-guarded).sodium/NOTES.mddocuments the process.Improvement 1 — cross-implementation advisory:
IMPLEMENTERS.md: portable writeup of the replay-protection integer overflow and the STANDARD.md errata for the C#/Go/Rust/TypeScript port maintainers to check against. Linked from README. (Filing issues on those third-party repos is held pending your go-ahead — see PR discussion.)Notes
