feat(@angular/cli): add aube as supported package manager

[santoshyadavdev]

Add support for the aube package manager, a Rust-based Node.js package manager that is fully compatible with the npm ecosystem.

Aube is a drop-in replacement for npm/pnpm/yarn/bun that focuses on speed, automatic installs before script execution, and cross-project package deduplication via a content-addressable store.

Key characteristics:

• Binary: aube
• Lockfile: aube-lock.yaml
• Commands: aube add, aube install, aube view --json, aube list --json
• Config: .npmrc (shared with npm/pnpm)
• JSON output: Mirrors npm/pnpm format, so existing parseNpmLike* parsers are reused

Changes:

• Add aube descriptor to SUPPORTED_PACKAGE_MANAGERS in package-manager-descriptor.ts
• Add aube to PACKAGE_MANAGER_PRECEDENCE
• Update workspace schema JSON (workspace-schema.json) — both cliOptions and cliGlobalOptions
• Update ng-new/schema.json and workspace/schema.json schematics
• Update @angular/create to detect aube from npm_config_user_agent
• Add aube lockfile discovery test
• Add aube support to e2e test utilities

Testing:

• All existing CLI unit tests pass (bazel test //packages/angular/cli:test — PASSED)
• Added discovery spec test for aube-lock.yaml
• Tested with a new workspace and the app works fine

Closes #34057

Code Review

This pull request introduces support for a new package manager named 'aube' across the Angular CLI, including schema updates, lockfile discovery, package manager descriptors, and e2e test utilities. The feedback suggests adjusting the package manager precedence to place 'bun' above 'aube' since 'bun' is more widely established.

[gemini-code-assist]

Since bun is a significantly more established and widely used package manager in the community compared to aube, it is safer to place bun higher in the precedence list. If a project contains both bun.lockb and aube-lock.yaml, bun is much more likely to be the intended primary package manager.

Suggested change

	export const PACKAGE_MANAGER_PRECEDENCE: readonly PackageManagerName[] = [
	'pnpm',
	'yarn',
	'aube',
	'bun',
	'npm',
	];
	export const PACKAGE_MANAGER_PRECEDENCE: readonly PackageManagerName[] = [

	'yarn',
	'bun',
	'aube',
	'npm',
	];

Thanks for raising this!

Whlist aube certainly looks interesting, we think it’s a bit early to look into Angular support. We'll keep an eye out for stronger interest from the Angular community before taking next steps.
