Ran `socket fix --all --range-style preserve --minimum-release-age 7d`. Pinned ethers to 5.7.0 (exact) afterward — socket fix wanted to bump ethers v5 → v6 (a breaking API change) and we cannot adopt v6 yet.

Note
Low Risk
Changes are limited to package-manager config and documentation; no runtime swap plugin logic is touched. Contributors should watch for the README setup typo and any CI (e.g. Jenkins) still invoking
yarnoutside this diff.Overview
This PR migrates the repo from Yarn to npm as the documented package manager.
Tooling and config:
.yarnrcis removed and replaced with.npmrc(legacy-peer-deps=true,ignore-scripts=true)..gitignoreno longer ignorespackage-lock.json, so the lockfile can be committed with npm installs.Docs and scripts: README,
docs/CHAIN_MAPPING_SYNCHRONIZERS.md,docs/CREATING_AN_EXCHANGE_PLUGIN.md, andconvert.shnow usenpm install/npm run …instead ofyarn/yarn mapctl ….Note: The README “Adding Your Exchange” block shows
npm run npm install prepare, which looks like a mistaken conversion ofyarn && yarn prepareand may not run as intended.Reviewed by Cursor Bugbot for commit 82007b0. Bugbot is set up for automated code reviews on this repo. Configure here.
