Configure ignore rules globally

Before I push this global ignore to other devs, make the common patterns visible. Produce a proposed global exclude that covers editor swap files, OS metadata, and IDE folders we never commit. Add comments explaining why each pattern exists and flag any patterns that risk hiding files we might want to track (for example, .env). Ladder":"L2"

I added *.log to my global exclude and my repository still shows server.log as untracked. I am worried the file is already tracked or my global exclude is misconfigured, and I cannot tell which. What is the likely reason and the quickest command to prove whether server.log is already tracked by the repo? Ladder":"L5"

Across projects we keep committing OS files and IDE folders because new engineers set different local ignores. This causes noisy diffs and wasted code-review time. Recommend one team habit and one repo-level change that will reduce accidental commits of junk across all developers. Ladder":"L6"
