Remove deprecated unsafe-perm setting from .npmrc

[Copilot]

Problem

Running npm install or npm run build produces the following warning on every invocation:

npm warn Unknown project config "unsafe-perm". This will stop working in the next major version of npm.

This warning appears repeatedly during the build because each sub-command also triggers it, resulting in many lines of noise in the output.

Fix

Removed the deprecated unsafe-perm = true line from .npmrc. This setting is no longer recognized by modern npm versions and has no effect. The remaining .npmrc settings (package-lock=false and save-exact=true) are unaffected.

Verification

• npm install produces zero warnings
• npm run build completes with zero warnings
• npm run lint passes
• npm run check-types passes
