doc: add git pull reminder before branching in AGENTS.md Critical Reminders #329

Description
The Critical Reminders section in AGENTS.md documents the Flow as: Issue -> Branch -> Commit -> PR -> Merge. But it doesn't mention syncing local main with remote before creating a branch.
AI agents can have a stale local main (e.g., after dependabot PRs are merged via GitHub web UI), causing branches to be based on old commits and PRs to show as "out of date".
Add to the Flow reminder: Always git pull origin main before creating a branch — local main may be behind the remote.
Applied downstream in endavis/pynetappfoundry#459.
