chore(remix): replace glob with native recursive fs walk

[roli-lpci]

Replaces the glob dependency in @sentry/remix with a simple recursive fs.readdirSync walk for finding .map files to delete after source map upload.

• If you've added code that should be tested, please add tests.
• Ensure your code lints and the test suite passes (yarn lint) & (yarn test).
• Link an issue if there is one related to your pull request. If no issue is linked, one will be auto-generated and linked.

Ref #19447

What this does

Replaces glob.sync('**/*.map', { cwd: buildPath }) in deleteSourcemaps.js with a manual recursive directory walk using native fs.readdirSync. This removes the glob package and its transitive dependency tree (minimatch, brace-expansion, balanced-match, minipass, jackspeak, path-scurry, foreground-child) from @sentry/remix.

Also cleans up orphaned glob/jackspeak/path-scurry resolution overrides in the integration test package.json.

Why manual recursion instead of fs.readdirSync({recursive: true})

fs.readdirSync(dir, { recursive: true, withFileTypes: true }) silently drops entries on Node 18.17-18.18 due to a known Node.js bug. Since @sentry/remix supports Node >= 18, a manual recursive walk avoids this edge case entirely.

Behavioral notes

• The walk returns relative paths from buildPath, matching glob.sync's { cwd } output shape
• Non-existent directories return [] gracefully (matching glob behavior)
• The walk includes dotfiles (glob excludes by default with dot: false), but this has zero practical impact since Remix build output never produces .map dotfiles
