Krzysztof kuhy Rudnicki 8a556f8d7d Cache .mypy_cache so mypy stops re-analysing the stdlib every run ... Profiled the 23s hook step per hook. It is not evenly spread: mypy ~10s and pylint ~9s are the whole of it, and the remaining 21 hooks share ~4s. Local timings with a warm cache put mypy at 0.25s against 5.7s cold, so nearly all of its CI cost is re-analysing the stdlib and third-party stubs from scratch into a 19MB cache dir that was then thrown away. Keyed on the config rather than on the sources. The mypy cache metadata already records the interpreter, the flag set and a hash per source file, so mypy re-checks whatever actually changed and a restored cache cannot let stale code pass. The config hash is in the key regardless, so bumping the mypy rev or editing its args busts it. Deliberately not keyed on github.sha, which is the other common pattern: that re-saves 19MB x3 on every commit and would evict the 68MB hook caches under the 10GB LRU budget for the repo. A fixed key keeps the dependency analysis, which is the part that costs the 10s. pylint needs no change -- it already runs --jobs=4.
