### Breaking Changes
- Resource precedence for extensions, skills, prompts, themes, and slash-command name collisions is now project-first (`cwd/.pi`) before user-global (`~/.pi/agent`). If you relied on global resources overriding project resources with the same names, rename or reorder your resources.
- Extension registration conflicts no longer unload the entire later extension. All extensions stay loaded, and conflicting command/tool/flag names are resolved by first registration in load order.
