This PR changes all `lean-toolchain` to use relative toolchain paths instead of `lean4` and `lean4-stage0` identifiers, which removes the need for manually linking toolchains via Elan. After this PR, at least Elan 4.2.0 and 0.0.224 of the Lean VS Code extension will be needed to edit core. Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com> |

mergeSortBenchmark
Benchmarking List.mergeSort.
Run lake exe mergeSort k to run a benchmark on lists of size k * 10^5.
This reports the average time (in milliseconds) to sort:
- an already sorted list
- a reverse sorted list
- an almost sorted list
- and a random list with duplicates
Run python3 bench.py to run this for k = 1, .., 10, and calculate a best fit
of the model A * k + B * k * log k to the observed runtimes.
(This isn't really what one should do:
fitting a log to data across a single order of magnitude is not helpful.)
