fix: recompile agents during module update to get latest source changes

The update() and updateCore() methods were only syncing files without
recompiling agents. Since compiled .md agent files are always newer
than their source .agent.yaml files, mtime-based skip logic prevented
agent updates.

Now both methods call compileModuleAgents() after syncing, ensuring
agents are rebuilt from fresh source YAML. User customizations remain
safe in separate .customize.yaml files.

Fixed in two places:
- ModuleManager.update() for module agents (bmm, bmb, etc.)
- Installer.updateCore() for core agents (bmad-master)
