docs: improve README quickstart

[parker-ekwis-bot]

This updates the README to be clearer for new users.

• Adds a Quickstart (venv + install + example query)
• Adds a short "Using this template" section
• Clarifies what the included scripts do

Notes:

• Docs-only change (no code changes)
• Tests not run (README update only)

@mattknight23 would appreciate your review when you have a minute.

Hi @mattknight23 — quick docs polish pass to make the template easier to pick up.

Main changes:

• Added a short Quickstart (venv + install + example query)
• Added a brief ‘Using this template’ section
• Tightened script descriptions + troubleshooting

No code changes here; just README wording/structure. Thanks!

Follow-up after a full repo skim: I expanded the README so it doesn’t lose important setup/usage info, while keeping it concise.

Updates in latest commit:

• Added a short configuration overview ( + )
• Clarified SObject Collections usage vs the Bulk API helpers in
• Added clearer testing guidance (unit vs integration; integration creates/deletes Case records)
• Fixed/clarified placeholders (incl. )

@mattknight23 would love your eyes when you have a moment.
