Date: Wed Feb 14 21:39:31 2024 +0100 Timestamp: 1707943171 Use node counting to early stop search This introduces a form of node counting which can be used to further tweak the usage of our search time. The current approach stops the search when almost all nodes are searched on a single move. The idea originally came from Koivisto, but the implemention is a bit different, Koivisto scales the optimal time by the nodes effort and then determines if the search should be stopped. We just scale down the `totalTime` and stop the search if we exceed it and the effort is large enough.

The screenshot below shows the execution logic of the reworked ci, https://github.com/Disservin/Stockfish/actions/runs/7773581379. You can also hover over the cards to see the execution flow. The `matrix.json` and `arm_matrix.json` define the binaries which will be uploaded to GitHub. Afterwards a matrix is created and each job compiles a profile guided build for that arch and uploads that as an artifact to GitHub. The Binaries/ARM_Binaries workflow's are called when the previous step has been completed, and uploads all artifacts to the (pre)release. This also fixes some indentations and renames the workflows, see https://github.com/official-stockfish/Stockfish/actions, where every workflow is called `Stockfish` vs https://github.com/Disservin/Stockfish/actions. It also increases the parallel compilation used for make from `-j2 to -j4`. It now also prevents the prerelease action from running on forks.
