Org migration: update Go module paths (zeevdr → opendecree)

[zeevdr]

Description

The critical migration step. Update all Go module paths from `github.com/zeevdr/decree` to `github.com/opendecree/decree`.

Files to update

go.mod files (8 modules)

• `go.mod` — root module
• `api/go.mod`
• `sdk/configclient/go.mod`
• `sdk/adminclient/go.mod`
• `sdk/configwatcher/go.mod`
• `sdk/tools/go.mod`
• `cmd/decree/go.mod`
• `e2e/go.mod`

Each needs:

• Module path updated
• All `require` lines referencing zeevdr updated
• All `replace` directives updated

All .go source files

• Every `import "github.com/zeevdr/decree/...` → `"github.com/opendecree/decree/...`
• Estimated ~100+ files

go.work

• All module paths updated

Other Go-adjacent files

• `.goreleaser.yml` — module paths
• `buf.yaml`, `buf.gen.yaml` — if they reference Go module paths
• `Makefile` — any hardcoded paths

Approach

```bash

Bulk rename across all Go files

find . -name '*.go' -o -name 'go.mod' -o -name 'go.work' | xargs sed -i 's|github.com/zeevdr/decree|github.com/opendecree/decree|g'
```

Then run `go mod tidy` in each module and verify with `go build ./...`

Depends on

• Org migration: create fresh repos with clean history #170 (fresh repos created)

Acceptance criteria

• All 8 go.mod files updated
• All .go imports updated
• `go build ./...` succeeds
• `go test ./...` passes
• `go vet ./...` clean

Completed — migrated to opendecree org.
