♻️ Make GO_MODE canonical; MODE becomes alias ♻️

Browse Source 
GO_MODE fits the GO_* naming convention. MODE is kept as a convenience alias.
Resolution order: GO_MODE → MODE → GO_PROD=1 (legacy).
- rootfs/usr/local/bin/go-workflow: resolve _RESOLVED_MODE from GO_MODE with
MODE as fallback; warn message now references GO_MODE; logic otherwise unchanged
- README.md: rename MODE row to GO_MODE (canonical); add MODE row as alias;
update production mode section to use GO_MODE=prod

### Production mode
Set `MODE=prod` to strip binaries for release: `-trimpath` removes all local
file system paths; `-ldflags=-s -w` strips the symbol table and DWARF debug
info. Applied to `go build` only — `go test` is unaffected so stack traces
stay readable.

`MODE=production` is also accepted. `GO_PROD=1` is a legacy alias that still
works when `MODE` is not set.
