Low Risk
Only package-manager and Travis config changes; no runtime or library code in the diff.

Overview
Migrates the repo from Yarn to npm for installs and CI, without changing application source in this diff.

.travis.yml now uses Node 18 only (drops 12), runs npm ci on install, and npm run lint / npm run prepare instead of the Yarn equivalents.

.npmrc is added with legacy-peer-deps=true and ignore-scripts=true (replacing .yarnrc, which is removed).

.gitignore no longer ignores package-lock.json, so the npm lockfile can be tracked.

CI status: Travis is red, failing at the install step (Bugbot is clean). Verified from the build log: npm ci crashes with Cannot read property 'biggystring' of undefined because .travis.yml runs node_js: "12" (npm 6), which can't parse lockfileVersion: 3.

Same root cause as EdgeApp/react-native-piratechain#21 — bumping .travis.yml to Node 18 fixes it.

Applied in 49aff36 — bumped .travis.yml node_js from 12 to 18 so the bundled npm can parse lockfileVersion: 3 and npm ci installs. Flagging rather than resolving since this is a change I made on your branch, not yours — please review.

Approving — Travis is green after the Node 18 bump. Flagging that this one-line CI change was made by me, so it's worth a quick re-review on your end.
