Add blueprint preflight hooks

[kezaer]

Stack:

1. Add Go2 local Wi-Fi doctor dimensionalOS/dimos#2378 - Add Go2 local Wi-Fi doctor
2. This PR - Add reusable blueprint/hardware preflight infrastructure
3. feat/go2-startup-autodetect - Apply it to Go2 startup connectivity
4. feat/go2-teleop-lan-setup - Harden Go2 LAN teleop/browser setup

Summary:

• Add Blueprint.preflights(...) and run_preflights(...) so startup checks can validate or conservatively repair GlobalConfig before module deployment.
• Stage config updates atomically, reject direct config mutation from preflights, and skip owner-scoped preflights when their owning module is disabled.
• Add generic single-target and multi-target hardware preflight helpers with fail-closed defaults for configured replacements and discovered fleet selection.
• Tighten coordinator rollback behavior for deploy failures and clean up pytest watchdog subprocesses.
• Complete the local pygame key stub so full mypy can validate the stack from a clean worktree.

Why:

• DimOS startup should make safe, typed, reusable decisions before workers and hardware modules start, rather than embedding one-off robot setup logic in individual launch paths.
• Hardware auto-repair should be conservative: fill only unambiguous missing config and fail closed when a configured target does not validate.
