Devtools fixes ambiguous Map keys, eslint-plugin-vue rules move to TypeScript

By RepoJournal · Filed · About Vue.js · Composed from the cited sources · methodology

Vue Devtools closed a state-inspector bug that could lock a Map entry out of editing entirely, and eslint-plugin-vue continued its TypeScript migration with eleven directive validators.

fix(state): avoid ambiguous Map keys during edits vuejs/devtools

by shuaiyafei

Renaming a Map entry to a label that already existed (for example a numeric 1 and the string "1") used to pass Map.has and write a second key with the same displayed label, after which state-path resolution rejected the label as ambiguous and neither entry could be edited or deleted through the inspector.

by Arlo

Dead code from earlier versions is gone: the content script read window.__VUE_DEVTOOLS_VITE_PLUGIN_CLIENT_URL__ into the extension's detection payload, but nothing set that global and nothing read the field. It is removed from shared/detection.ts, content/backend.ts, background/tab-state.ts and the related unit test.
