Expected behavior

A file with a /* global Office ... */ comment, as the OfficeDev templates write them, lints cleanly with configs.recommended and with office-addin-lint check.

Current behavior

Since 5.0.0 the recommended config declares Office, Excel, Word and the other Office.js namespaces in languageOptions.globals (main.ts#L42-L51), added for #999. It also spreads @eslint/js recommended (main.ts#L24), which turns on no-redeclare. That rule's builtinGlobals option is true by default, and with it the rule reports a /* global */ comment for a name that is already a configured global.

The templates have such a comment in their task pane and command files, e.g. Office-Addin-TaskPane src/taskpane/excel.ts#L6 (/* global console, document, Excel, Office */), Office-Addin-TaskPane-JS src/commands/commands.js#L6 and Office-Addin-TaskPane-React src/taskpane/outlook.ts#L1. They still pin eslint-plugin-office-addins ^4.0.10 and office-addin-lint ^3.0.10, so npm run lint starts failing on each of those files once they move to the current majors. In an Outlook add-in I work on, the update to office-addin-lint 4.0.1 and eslint-plugin-office-addins 5.0.1 gave 19 no-redeclare errors, one per file with such a comment.

Steps to Reproduce

mkdir repro && cd repro && npm init -y
npm i -D office-addin-lint@4.0.1 typescript@5.9.3
mkdir src
printf '/* global Office console */\n\nOffice.onReady(() => {\n  console.log("ready");\n});\n' > src/taskpane.ts
npx office-addin-lint check

src/taskpane.ts
  1:11  error  'Office' is already defined as a built-in global variable  no-redeclare

✖ 1 problem (1 error, 0 warnings)

configs.recommended used directly gives the same error under ESLint 9.39.5 and 10.12.0. With eslint-plugin-office-addins 4.0.10 the same file has no errors.

Context

• Operating System: macOS
• Node version: 26.0.0
• Office version: n/a
• Tool version: eslint-plugin-office-addins 5.0.1, office-addin-lint 4.0.1, eslint 9.39.5 and 10.12.0

Failure Logs

See above. Setting "no-redeclare": ["error", { builtinGlobals: false }] in the recommended config keeps the globals from #999, accepts the comments and still reports a variable declared twice; I have a PR ready.
