zeekayandHanzo Dev 3b21ff252e build: bump Go builder images to 1.26.5, set GOTOOLCHAIN=auto
Currency bump: golang builder images -> 1.26.5 (latest stable).

Adds ENV GOTOOLCHAIN=auto to each Go builder stage. The official golang
images set GOTOOLCHAIN=local, so a builder image older than the module's
go directive is a hard mid-build failure. The pin stays the hermetic fast
path; auto is the safety net for the next go.mod bump.

No go.mod go directive was changed. Builder images move; directives stay.
