fix: auto-merge must use PAT_TOKEN to trigger downstream workflows

[cloud-hai-vo]

Problem

PR #83 merged via auto-merge but publish, CI, and benchmarks did NOT run on the resulting push to main.

Root Cause

GitHub limitation: pushes made by GITHUB_TOKEN do NOT trigger other workflows. PR #79 switched auto-merge to GITHUB_TOKEN to control the merge actor identity. But this silently broke all downstream workflow triggers.

Why it wasn't caught earlier

PR #82 was manually merged (not auto-merge) → publish ran → v1.15.0. PR #83 was auto-merged → publish silently skipped.

Fix

• Auto-merge: switch back to PAT_TOKEN — merge pushes now trigger all downstream workflows
• Publish: restore paths: ['src/**'] filter — prevents publishing on README-only benchmark merges (which will now also trigger pushes via PAT_TOKEN)
• Benchmarks: already has path filter — no change needed

After this merges

Run workflow_dispatch on publish to catch up on the missed v1.15.1 (PR #83 changes).

Test plan

• After this PR merges, next code PR should trigger publish
• Benchmark README PRs should NOT trigger publish (path filter)

📝 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 '*'
