fix(install): stop --frozen rewriting the lockfile it freezes - #2384

Advisory evidence only. This check never authorizes implementation or merge.

State: needs-evidence. Candidate issue links are metadata, not proof the implementation matches scope. Fresh human confirmation remains required.

• Issue #2379: manual-review. The linked issue is closed; a human must confirm any remaining scope.
• Issue #2380: not-an-issue. A PR reference is not issue traceability.
• Issue #2381: not-an-issue. A PR reference is not issue traceability.

A current comment scan cannot detect a deleted withdrawal. Confirm current bounded scope,
implementation-to-scope match and review support with a responsible human.
Use CONTRIBUTING.md and the trusted default-branch GOVERNANCE.md roster.
Private security tracking stays private. No labels, milestones or code reviews substitute for scope approval.
