Summary

Fixes #7950. Removes the --unsafe-perm flag from the three sites that pass or require it: npm 12 rejects unknown CLI flags (EUNKNOWNCONFIG) so the install dies before starting. The flag has been behaviorally irrelevant since npm v7.0.0 (2020): the changelog says the user/group/uid/gid/unsafe-perms configs are 'no longer relevant.' Scripts run as the working-dir owner regardless.

Changes

2 files: install.sh (drop flag from global install) + ci/build/npm-postinstall.sh (remove root guard that errors unless unsafe_perm=true, drop flag from dev-install). Validation: grep zero unsafe-perm refs, bash -n syntax OK, npm run test:scripts 34/34 pass.

Repro

before: npm 12 + install -g code-server --unsafe-perm -> EUNKNOWNCONFIG. Follow-up tracked separately: npm 12 blocks postinstall scripts unless --allow-scripts is configured.

npm 12 rejects unknown CLI flags, so the npm install path crashes
with EUNKNOWNCONFIG before installing. The flag has been a no-op
since npm 7; remove it from install.sh and the postinstall guard.
Closes coder#7950.
