chore(deps): align the SILO Go dependency stack

Standardize the related SILO components on Go 1.27 tooling, etcd 3.7.1, current Go-maintained modules, shared runtime versions, and explicit security and portability pins.

Keep the shared package Go 1.26 consumer floor, isolate lint tooling from product dependency selection, and preserve upstream-compatible import paths.
