chore(submodules): bump eyrie to cac004d (post-#46 squash) (#62)

- eyrie main now at cac004dae2e97 (refactor: make retry fallbacks and sqlite pooling configurable #46)
- hawk go.work replace still points at ./external/eyrie and resolves cleanly
- builds, vet, gofumpt, golangci-lint, and cmd+routing tests verify the new API surface (NewCodeAgentRetry variadic, storage.Open WithMaxOpenConns) is source-compatible with current hawk callers
