chore: cleanup — untrack binaries, consolidate Go dirs, dedupe tools

- Untrack and delete compiled binaries (tarsum, gosoft.exe, rust uniq/uniq2);
  ignore build outputs (dist/, bin/, *.exe, *.test, .ruff_cache/)
- Merge tools/go/ and projects/go-tools/go/ into projects/go-tools/<name>/
- Fix goipgrep .gitignore: bare 'ipgrep' pattern was ignoring cmd/ipgrep/,
  so the main entrypoint was never tracked; now anchored to /ipgrep
- Archive duplicate implementations to archive/experimental/{rust,go}/
  (uniq, between, tarsum rewrites); canonical versions stay in tools/
- Update README tool catalog to match new layout
