feat(rsc): show logs for build steps

[Copilot]

example

---

• Understand the current build flow and logging in plugin-rsc
• Add descriptive logging for each build phase in the buildApp function
• Test the changes with example builds to verify improved clarity
• Ensure the logging is consistent and informative
• Run linter and tests to verify no breaking changes
• Update terminology: "analyze dependencies" → "analyze server references"
• Update terminology: "build xxx" → "build xxx environment"

Changes Made

Enhanced build logging in @vitejs/plugin-rsc by adding simple info messages before each build step with improved terminology.

Result

Standard build (with SSR):

[1/5] analyze client references...
vite v7.1.10 building SSR bundle for production...
[2/5] analyze server references...
vite v7.1.10 building SSR bundle for production...
[3/5] build rsc environment...
vite v7.1.10 building SSR bundle for production...
[4/5] build client environment...
vite v7.1.10 building for production...
[5/5] build ssr environment...
vite v7.1.10 building SSR bundle for production...

No-SSR build:

[1/4] analyze client references...
vite v7.1.10 building SSR bundle for production...
[2/4] analyze server references...
vite v7.1.10 building for production...
[3/4] build rsc environment...
vite v7.1.10 building SSR bundle for production...
[4/4] build client environment...
vite v7.1.10 building for production...

The changes use simple logger.info() calls before each build to provide clear progress indicators with step numbers and accurate descriptions.

Can we improve Vite logger to make it clear about what each step of these 5 builds do?

@copilot let's not patch logger. let's start with just log something before each build.

@copilot let's not patch logger. let's start with just log something before each build.

Updated to use simple logger.info() calls before each build instead of patching the logger. Commit: 87c4ea4

Build output now shows:

[1/5] analyze client references...
vite v7.1.10 building SSR bundle for production...
[2/5] analyze dependencies...
vite v7.1.10 building SSR bundle for production...
[3/5] build rsc...
vite v7.1.10 building SSR bundle for production...
[4/5] build client...
vite v7.1.10 building for production...
[5/5] build ssr...
vite v7.1.10 building SSR bundle for production...

@copilot "analyze dependencies..." should be "analyze server references...".

"build xxx" should be "build xxx environment"
