fix: benchmark PRs now trigger CI builds for branch protection

[cloud-hai-vo]

Problem

PR #77 (benchmark README update) has no CI build because the commit message contains [skip ci]. This prevents branch protection checks from passing, so the PR can't be merged.

Root Cause

The benchmark workflow added [skip ci] to prevent infinite loops (benchmark push → triggers benchmark → pushes again). But this also skips the CI build/test workflow needed for branch protection.

Fix

• Remove [skip ci] from benchmark commit message — CI now runs normally on the PR
• Publish workflow: change guard from [skip ci] message check to github.actor != 'github-actions[bot]' — prevents NuGet publish for bot-authored README-only merges
• No infinite loop risk: benchmark workflow already has if: github.actor != 'github-actions[bot]' guard

Test plan

• Next benchmark PR should show CI build status
• Merging benchmark PR should NOT trigger publish workflow

📝 Notes

• Each benchmark class is decorated with [MemoryDiagnoser] and [RankColumn].
• The global config (see src/EggMapper.Benchmarks/Program.cs) adds Min, Median, and Max columns.
• Manual is the hand-written baseline (ratio = 1.00). A ratio < 1 means faster than manual.
• Benchmarks run on GitHub-hosted runners — absolute times may vary between runs; focus on Ratio for comparisons.
• To reproduce locally:

  cd src/EggMapper.Benchmarks
  dotnet run --configuration Release -- --filter '*'
