docs: perfSONAR toolkit installer updates (fetch more helpers, version bump)

[ShawnMcKee]

Cleaned PR description: installer & lsregistration helper updates

Summary

• Installer (install_tools_scripts.sh): bump to 1.0.1 and expand fetch behavior to provide a fuller set of helper scripts and documentation files. The installer now attempts to download accompanying .sha256 checksum files when present.
• Added to installer fetch list: fasterdata-tuning.sh, repair-state-json.sh, and other recent helper scripts so bootstrap installs get the latest tooling.
• Checksums: added/updated .sha256 files for modified scripts under docs/perfsonar/tools_scripts/ so verification scripts can validate releases.
• lsregistration helper (perfSONAR-update-lsregistration.sh): improved restart behavior to better support RPM (non-container) installs by preferring the perfsonar-lsregistrationdaemon unit when present, falling back to lsregistrationdaemon, and finally to signalling the process; encapsulated restart logic in helper functions.
• Docs: updated CHANGELOG.md, README-lsregistration.md, and install-perfsonar-toolkit.md to document these changes.

Testing & reviewer checklist

1. Run the installer on a staging host and verify /opt/perfsonar-tp/tools_scripts contains the expected scripts and .sha256 files.
2. Verify checksum consistency for key scripts (example):
   • sha256sum /opt/perfsonar-tp/tools_scripts/fasterdata-tuning.sh
   • Compare result with the contents of fasterdata-tuning.sh.sha256 in the same directory.
3. Test perfSONAR-update-lsregistration.sh in both modes:
   • Container mode (default): confirm it copies, updates, and restarts inside the running perfsonar-testpoint container.
   • Local mode (--local): confirm it writes to /etc/perfsonar/lsregistrationdaemon.conf and attempts to restart perfsonar-lsregistrationdaemon (or falls back to lsregistrationdaemon).
4. Optionally run shellcheck on modified scripts for style/safety checks.

Notes

• I verified checksums locally and confirmed the installer fetch list includes the newly-added helpers.
• I also updated install_tools_scripts.sh.sha256, perfSONAR-update-lsregistration.sh.sha256, and other relevant checksum files.

If you want, I can squash commits, add more documentation examples, or merge the PR when it's approved.
