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

Reverts to GitHub Actions cache (from custom S3 implementation) while preserving all bug fixes and improvements from PR #623. Key changes: - Replace custom S3 cache actions with actions/cache@v4 - Remove AWS credentials from workflows - Restore dual-cache system (main + feature branch with secondary_storage) - Add cache clearing via GitHub API (replaces S3 delete operations) - Create reusable xahau-ga-clear-cache action (DRY) - Fix conanfile.txt → conanfile.py in cache keys Bug fixes preserved: - Wrapper toolchain: prevents Conan from overriding ccache settings - Configuration ordering: ccache/Conan config applied AFTER cache restore - Single ccache directory with secondary_storage for feature branches - Verbose build flag support: [ci-ga-cmake-verbose] - Branch comparison logic removed for Conan cache saves Cache clearing features: - [ci-ga-clear-cache] - Clear all caches for this job - [ci-ga-clear-cache:ccache] - Clear only if key contains "ccache" - [ci-ga-clear-cache:conan] - Clear only if key contains "conan" - [ci-ga-clear-cache:gcc Debug] - Clear if key contains both terms (AND logic) - Uses gh CLI with github.token (no additional credentials needed) Rationale: GitHub increased cache limits, eliminating need for S3. This approach maintains all performance improvements while simplifying infrastructure. Fixes #620 Fixes #618
