Cache key isolation: Include the build flavour (ccwarn/asan/gcov) in the build ccache key, so the coverage (gcov), asan, and RTLMeter (ccwarn-off) configurations no longer share and thrash the single '<runs-on>-<cc>' bucket, nor warm-start from each other's (near-useless) caches. Prune stale entries instead of a fixed size cap: After building/testing, evict ccache entries this run did not touch (--evict-older-than, based on the run's own duration). This bounds the saved cache to the current working set, so CCACHE_MAXSIZE and CCACHE_LIMIT_MULTIPLE are no longer needed and are removed (ccache falls back to its 5G default ceiling, but is realistically much smaller). ccache configuration: - Drop CCACHE_COMPRESS (already the default in ccache 4.x). - Add CCACHE_COMPILERCHECK=content, so a changed compiler mtime on a rebuilt ephemeral runner image does not invalidate the whole restored cache. - Hoist all ccache-related variables (CACHE_BASE_KEY, CCACHE_*, CXX) to the workflow-level env. Remove dead ccache scaffolding: - reusable-lint-py: the job never compiles or caches; drop its ccache env. - reusable-rtlmeter-run: remove the disabled persistent-cache step and its storage variables; keep CCACHE_DISABLE=1, since caching must stay off to keep RTLMeter timings representative. Store test job ccache as artifacts for reuse
