[WRONG BRANCH] fix(cli): preserve service command exit failures - #260

Motivation

• The service dispatch runner unconditionally returned 0, masking failure statuses set by serviceCommand via process.exitCode and causing ocx service to report success when the service was not actually serving.

Description

• Make dispatchCommand propagate the service runner's observed exit status by adding a serviceCommand dependency to CliDispatchDeps and calling await deps.serviceCommand(...) from the service runner. This returns Number(process.exitCode ?? 0) instead of 0. (src/cli/dispatch.ts).
• Wire the real serviceCommand through the top-level CLI entry so the runner receives the production implementation via deps (src/cli/index.ts).
• Add a focused regression test asserting that a non-throwing serviceCommand that sets process.exitCode = 1 causes dispatchCommand to return 1 (tests/cli-dispatch.test.ts).

Testing

• ✅ Ran the focused unit test: ./node_modules/.bin/bun test tests/cli-dispatch.test.ts, and the new test passed.
• ✅ Ran type checking: ./node_modules/.bin/bun run typecheck (bun x tsc --noEmit) and it passed.
• ⚠️ Ran the full test run ./node_modules/.bin/bun run test; the suite progressed with many passing tests but an unrelated test (CLI key-login live-update overlay preservation) timed out during the full run, so I only relied on the focused dispatch test and typecheck for verification.
