fix(0.81, macos-init): improve init flow and drop chalk dependency

[Saadnajmi]

Summary

• Remove redundant dependency install (generate-macos.js was running npm i/yarn a second time after cli.ts already installed react-native-macos)
• Show actual npm/yarn errors on install failure instead of swallowing them with --silent
• Validate peer dependencies before install and warn on version mismatch
• Fix finish message: remove nonexistent yarn start:macos, show correct pod install, npx react-native run-macos and npx react-native start
• Replace chalk with Node's built-in node:util styleText (available since Node 20.12), add engines.node field
• Re-enable integration test CI without Verdaccio (fixes ci: re-enable verdaccio dependent tests #2344) — installs local package directly via npm install <path>

Motivation

Users hitting npx react-native-macos-init frequently encounter silent failures from peer dependency mismatches (e.g. react-native-macos@0.81.4 requires react-native@0.81.6 exactly, but --version 0.81 installs the latest patch). The --silent flag hid the actual error. The finish message referenced a nonexistent yarn start:macos script.

Addresses the same root issue as #2785 and #2793 but with a broader fix.

Backport of #2858.

Test plan

• Created a new project with npx @react-native-community/cli init testapp --version 0.81.6
• Ran modified init — happy path: no peer dep warning, correct finish message
• Tested mismatch path (react-native@0.81.5 vs required 0.81.6) — warning fires before install with clear message
• TypeScript compiles cleanly
• Re-enabled CI integration test (no longer depends on Verdaccio)

Pull request overview

This PR updates the macOS init/generation flow to reduce redundant installs, improve user-facing install diagnostics, and remove the chalk dependency by switching to Node’s built-in node:util styling.

Changes:

• Remove the second dependency installation step from the macOS generator path.
• Improve react-native-macos-init install behavior by surfacing real npm/yarn errors and warning early on peer dependency mismatches.
• Replace chalk usage with node:util styleText and update the post-generation “next steps” instructions.
