chore(deps): upgrade Angular 20 → 21

Migrates to Angular 21.0.0: updates tsconfig lib to es2022, migrates
bootstrap options in main.ts, and completes control flow migration
(*ngFor/*ngIf → @for/@if) in jumps and jumps-by-month templates to
resolve duplicate ng-template name conflicts skipped by the schematic.
Also fixes pre-commit hook to load nvm before running tests.
