Yuneng Jiang b39f210a6c [Infra] Add freshness and destructive guards to migration workflow
Generating a migration from a stale branch could silently emit DROP
COLUMN for columns the stale branch did not know about, and the
script would write that SQL to a new migration file with no warning.

Adds two guards to ci_cd/run_migration.py:

- Branch freshness check: fetches origin/<base-branch> and exits 3 if
  HEAD is behind. Default base is litellm_internal_staging. New
  flags: --base-branch, --skip-freshness-check.
- Destructive guard: refuses (exit 2) if the generated diff contains
  DROP COLUMN / DROP TABLE / DROP INDEX, unless --allow-destructive
  is passed.

Refusal banners include guidance and an explicit callout instructing
AI agents not to auto-bypass the flags. Also treats Prisma's
"-- This is an empty migration." output as a no-op rather than
writing an empty file.

Updates litellm-proxy-extras/migration_runbook.md with the new
workflow, flag documentation, and agent warnings.
