Subject: [PATCH] ci(release): fix duplicate tag error in multi-crate workspace

release-plz was creating the same v{{ version }} tag for both loom-cli
and loom-core, causing "Reference already exists" on the second crate.

Fix: disable git_tag_enable at workspace level, enable it only on
loom-cli (the primary package). loom-core inherits the disabled default.

See: https://release-plz.ieni.dev/docs/extra/single-tag
See: https://github.com/release-plz/release-plz/issues/2292
