Add rolldown version testing tool with statistics collection (stable versions only)

[Copilot]

This PR implements a comprehensive tool for testing the vibe-dashboard across stable rolldown-vite versions, with automatic statistics collection and performance analysis capabilities.

Key Features

Dynamic Version Discovery

• Automatically fetches the last 5 stable versions from npm registry, sorted chronologically (oldest to newest)
• Real-time API integration ensures up-to-date version lists
• Focuses on stable releases for reliable testing

Comprehensive Statistics Collection
The tool includes a powerful --stats mode that automatically:

• Tests every available stable rolldown version (5 versions)
• Updates package.json, installs dependencies, and builds the app for each version
• Collects detailed file statistics from the dist directory
• Records build times, file sizes, and asset types
• Handles build failures gracefully and continues with remaining versions
• Saves comprehensive data to rolldown-version-stats.json for analysis

Streamlined Testing Workflow

# List all available versions
pnpm rolldown:list

# Test specific versions
pnpm rolldown:use 2          # Use second stable version
pnpm rolldown:use 7.1.2      # Use specific version

# Collect comprehensive statistics for all versions
pnpm rolldown:stats

Statistics Output
The generated rolldown-version-stats.json contains comprehensive data for performance analysis:

[
  {
    "version": "7.1.4",
    "timestamp": "2025-08-24T15:47:35.547Z",
    "files": [
      {
        "path": "assets/index-C_guGHi2.js",
        "size": 563794,
        "type": "js"
      },
      {
        "path": "assets/index-DD-rq4eS.css",
        "size": 2812,
        "type": "css"
      }
    ],
    "totalSize": 568609,
    "buildTime": 3420
  }
]

Analysis Results

Successfully analyzed 5 out of 5 available rolldown versions:

• Successful builds: 5 stable versions (showing chronological progression from oldest to newest)
• Failed builds: 0 (100% success rate with stable versions)
• Average build time: 3531ms
• Average bundle size: 555.77 KB

This enables comprehensive performance analysis across stable rolldown versions, making it easy to track bundle size changes and build time improvements as rolldown evolves.

Fixes #15.

@copilot for all past and future Rolldown versions fetched from the script, change the script and do the following, for every version

• update the rolldown version in apps/dashboard/package.json
• build the app
• collect file statistics from dist
• save the stats

Then for all the stats generated, save data into a json, the json is an array of all data collected of all versions of rolldown.

I've implemented comprehensive version statistics collection functionality as requested. The enhanced script now:

For every rolldown version (stable + experimental):

• Updates rolldown version in apps/dashboard/package.json
• Builds the app
• Collects detailed file statistics from dist directory
• Saves build metrics (file sizes, types, build time)

Key features:

• --stats command tests all 15+ available versions automatically
• Collects comprehensive data: file paths, sizes, types, build times
• Handles build failures gracefully and continues with other versions
• Saves all data to rolldown-version-stats.json as requested
• Automatically restores original package.json after analysis

Usage:

pnpm rolldown:stats
# or
node tool/override-rolldown.js --stats

The JSON output contains an array of statistics for each successfully built version, with detailed file information and build metrics. Commit: dd728e1

@copilot merge main and fix conflict

Successfully merged main branch and resolved all conflicts. The package.json conflicts were resolved by keeping both typescript-eslint and the updated rolldown-vite version, and the pnpm-lock.yaml was regenerated to ensure compatibility. All tests pass and linting is clean. Commit: a83f4c4

@copilot run rolldown:stats and commit the changes.

Successfully ran rolldown:stats command and committed the comprehensive statistics data. The analysis tested 15 available rolldown versions, with 5 successful builds generating detailed file statistics, build times, and bundle analysis. Results saved to rolldown-version-stats.json. Commit: fa1aca3

@copilot update lockfile

Updated lockfile to match current package.json dependencies. Commit: ab5c07e

@copilot future versions is broken, comment this line out and fix accordingly.

[Copilot]

Commented out the future versions functionality as requested. The fetchFutureVersions function call at line 311 and related code has been disabled. The tool now only analyzes stable versions from npm (5 versions), resulting in 100% successful builds. All unused functions and variables have been cleaned up to pass linting. Commit: 2a230d1
