Standalone binary from `build.ts --single` produces black screen + freeze

[jerome-benoit]

Description

The standalone binary produced by bun --bun ./script/build.ts --single --skip-install is broken on current dev. bun run dev works correctly.

This is release-blocking. script/build.ts --single is used by publish.ts to produce binaries for all distribution channels: npm, Homebrew, AUR, Docker, and Nix.

• 05d3e65f7 (feat: enable GitLab Agent Platform) → works
• d70099b05 (fix: apply Layer.fresh at instance service definition site — fix: apply Layer.fresh at instance service definition site #18418, @kitlangton) → broken — crashes with TypeError: undefined is not an object (evaluating 'Snapshot2.FileDiff.array')
• 214a6c6cf (fix: switch consumers to service imports to break bundle cycles — fix: switch consumers to service imports to break bundle cycles #18438) → broken — no longer crashes but black screen + freeze instead

The service/adapter split in d70099b05 introduces circular dependencies that break the bundled binary. PR #18438 attempts to fix the cycles but only turns the crash into a silent freeze.
