Angular 22 upgrades ESLint to v9, whose flat-config RuleTester no longer
accepts the top-level parser key. Use languageOptions.parser with an
imported @typescript-eslint/parser instead of require.resolve.

Prettier reflowed the guard condition, which moved a // @ts-ignore off the
line it suppressed and resurfaced TS2339 on memoize.numArgs. Give memoize
an explicit type so the extra properties are known without suppression.

Regenerate the lockfile so it matches the bumped package.json (restores
shiki and other main-only dependencies dropped during the merge).

Result of running the lint-staged formatters (prettier --write,
eslint --fix) repo-wide; no functional changes.

Replace deep relative imports into library source
(../../../libs/template/{push,unpatch,let}/src/lib/...) with the public
@rx-angular/template/{push,unpatch,let} entry points, resolving
@nx/enforce-module-boundaries violations surfaced by the ESLint 9 flat
config.
