Update

Zinc has two update paths:

zn update       updates the Zinc binary
zn pkg update   updates installed packages

They are separate.

Zinc binary

zn update --check
zn update

Standalone release binaries can self-update. Package-manager-owned binaries refuse self-replacement and print the manager command to use instead.

zn pkg update openai-responses --dry-run
zn pkg update openai-responses --global --yes
zn pkg update all --global --yes

Package update uses installed package URIs.

For git package URIs, Zinc checks matching package tags and updates only explicitly requested packages.

Example:

would update openai-responses 0.4.3 -> 0.4.4 openai-responses-v0.4.4

If current:

would update openai-responses 0.4.4 up to date at 0.4.4

neighbors is package-owned data. Zinc never installs, updates, resolves, or orders from it.
