[KB-13] knowledge_base: job_git_source #24

Roadmap ID: KB-13

Job using git_source plus the bundle.git branch check.

Acceptance criteria

• Deploy to prod fails from a non-main branch
• README explains git_source vs synced source

Edge-case checklist

• AWS / Azure / GCP support matrix (storage URIs, identity, node types, region availability)
• Serverless vs classic both validated, or the unsupported one documented
• No secrets in templates; use secret scopes / workload identity
• Dev schedules paused; no always-on costly resources in tests
• Re-deploy is idempotent; an interrupted deploy is safe to retry
• Teardown only removes resources the example owns
