feat: replace github actions cache with s3
Replaces actions/cache with custom S3-based caching to avoid upcoming
GitHub Actions cache eviction policy changes.
Changes:
- New S3 cache actions (xahau-ga-cache-restore/save)
- zstd compression (ccache: clang=323/gcc=609 MB, Conan: clang=1.1/gcc=1.9 GB)
- Immutability (first-write-wins)
- Bootstrap mode (creates empty dir if no cache)
Cache clearing tag:
- [ci-ga-clear-cache] - Clear all caches for this job
- [ci-ga-clear-cache:ccache] - Clear only ccache
- [ci-ga-clear-cache:conan] - Clear only conan
Configuration ordering fixes:
- ccache config applied AFTER cache restore (prevents stale cached config)
- Conan profile created AFTER cache restore (prevents stale cached profile)
ccache improvements:
- Single cache directory (~/.ccache)
- Wrapper toolchain (enables ccache without affecting Conan builds)
- Verbose build output (-v flag)
- Fixes #620
Conan improvements:
- Removed branch comparison logic for cache saves
- Cache keys don't include branch names, comparison was ineffective
- Fixes #618
Breaking changes:
- Workflows must pass AWS credentials (aws-access-key-id, aws-secret-access-key)
S3 setup:
- Bucket: xahaud-github-actions-cache-niq (us-east-1)
- Credentials already configured in GitHub secrets
