* feat: add --batch-size flag to push refs in batches Add support for pushing refs in smaller batches to avoid server-side limits and timeouts when syncing large repositories with many tags/branches. - Add --batch-size flag (default 0 = no batching, original behavior) - Add References() method to GitRepository interface - Implement collectRefs() and pushRefsInBatches() helpers - Add MinBatchSize validation (must be 0 or >= 10) This addresses issues where repositories with 1000+ refs fail to sync to GHES with 'command error on refs/heads/<branch>: failed' errors. * test: add tests for batch-size flag and push batching functionality * fix: pin tool dependencies to versions compatible with Go 1.21 * ci: fix docker compose v2 syntax and update setup-ruby action * refactor: address PR review feedback - Remove unused RefInfo struct from git.go - Remove redundant pushedAny variable tracking in pushRefsInBatches - Remove incomplete TestPushRefsInBatches_PartialUpToDate test (already covered by existing test case) * docs: add --batch-size flag to README
