fix(daemon): prefer active CLI for launchd

[roodboi]

Summary

• prefer the resolved active Hack CLI when writing or repairing the launchd service
• retain the global Hack binary as a fallback when no active executable is available
• cover mixed Homebrew plus stale local-development shim installs

Verification

• bun test tests/launchd.test.ts
• bun run check
• bun run typecheck
• bun run build
• bun test: 907 pass, 5 skip; one process-table test sandbox-blocked
• bun test tests/daemon-command.test.ts outside the restricted process sandbox: 1 pass
