ci(fuzz): pin gnu host target to fix musl+ASAN build failure #3

Workflow file for this run

name: fuzz
on:
# push: main — the ONLY auto-trigger. Each commit gets a fresh `github.sha`
# cache key, so libfuzzer's discovered corpus actually persists across runs
# (via the `restore-keys` prefix fallback). Path-filtered to skip docs-only
# or workflow-unrelated commits.
#
# No schedule cron: actions/cache is immutable per key, so scheduled runs
# on an unchanged SHA cannot save the corpus they discover — pure runtime
# cost with zero persistent benefit. For deep-fuzz sessions, use
# workflow_dispatch with a larger `duration_seconds` value.
