chore: reorganize project structure and remove build artifacts

- Move 10 experimental modules to src/nimsync/experimental/; keep
  backward-compatible re-export shims at old paths
- Remove 17+ committed ELF binaries and improve .gitignore coverage
- Fix version inconsistency: VERSION.nim and nimsync.nimble now both 1.1.0
- Delete orphan src/nimasync_simple.nim (typo filename, never exported)
- Remove deprecated root benchmarks/ folder and stale scripts/
- Remove duplicate docs/LICENSE and accidental benchmark CSV commits
- Move BENCHMARKS.md to docs/; untrack internal SUPPORT.md
- Fix nimble bench task to point to tests/performance/run_all_benchmarks.sh
- Add CHANGELOG entry for v1.1.1
