fix: update deployment run links

[nathanyoung]

related: https://github.com/Hyphen/hyphen-app/pull/1335

Summary

• Route deployment run links through internal/hyphenApp instead of formatting the legacy deployment URL inline.
• Prefer project/environment run URLs when deployment metadata is available, falling back to the legacy deployment route when it is not.
• Use the run deployment snapshot when it has route metadata so links survive selected deployment payloads without project/environment details.
• Add unit coverage for alternate IDs, ID fallbacks, legacy fallbacks, and snapshot selection.

Impact

Deployment commands now return app links that match the project/environment run route when enough metadata is available, while keeping the existing deployment URL fallback for incomplete payloads.

Validation

• env HOME=/private/tmp/hx-test-home GOCACHE=/private/tmp/hx-go-cache GOMODCACHE=/Users/nathanyoung/go/pkg/mod go test ./cmd/deploy ./internal/hyphenApp

Note: go test ./... was also attempted. The sandboxed run first hit Go build-cache permissions, then an isolated-home run passed acceptance coverage but failed internal/oauth because TestStartOAuthServer could not start its local OAuth callback server in this environment.

Code Review

This pull request refactors the deployment run link generation logic by moving it from cmd/deploy/deploy.go into a new helper function DeploymentRunLinkForRun in internal/hyphenApp/hyphenApp.go, and adds comprehensive unit tests. Feedback on these changes suggests passing the models.Deployment and models.DeploymentRun structs by pointer rather than by value to avoid inefficient copying and potential runtime panics from dereferencing a nil pointer.

Pull request overview

This PR updates how the CLI constructs deployment run links by routing them through internal/hyphenApp, preferring the newer project/environment run route when the deployment (or run snapshot) contains enough metadata, and falling back to the legacy deployment route otherwise.

Changes:

• Added DeploymentRunLink helpers in internal/hyphenApp that build project/environment run URLs when available, with a legacy /deploy/.../runs/... fallback.
• Updated cmd/deploy to use the centralized link builder instead of formatting the legacy URL inline.
• Added unit tests covering alternate IDs, ID fallbacks, legacy fallbacks, and snapshot-vs-selected deployment selection.
