improves the update message in case of global install.

[fabianboth]

In case the user installed globally, this gives a hint to proceed.

Greptile Summary

Improved the error message when package.json cannot be found at ~/.local/packages. The new message explicitly guides users who installed the CLI globally via npm to use npm update -g @octomind/octomind instead of showing a generic "please update manually" error.

• Enhanced user experience by providing actionable guidance for global npm installations
• Message now specifies the expected location (~/.local/packages) where the CLI looks for package.json
• Clear instruction for the alternative update method when the local package structure isn't present

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The change only improves an error message to be more helpful and actionable. No logic changes, no new functionality, and the improved message accurately reflects the two installation methods documented in the README
• No files require special attention
