extension-host: notices name the zod version the bundle ships

72cf7d9dfb regenerated dist/LICENSES.txt and builtin-modules.json for zod
4.6.7 but left THIRD_PARTY_NOTICES.md's heading at 4.6.5, so
extension_host::tests::every_package_in_the_bundle_has_a_licence_notice_and_a_third_party_entry
would fail its second pass: it requires every package in the embedded
Packages: list to appear as `name` version in the root notices file.

Verified by re-implementing that parse (Packages: section of
crates/tui/extension-host/dist/LICENSES.txt, split on " (", then rsplit '@')
over the tracked files: before this change [email protected] was the single missing
entry and `zod` 4.6.5 the single heading absent from LICENSES.txt; after it,
zero missing and zero absent across all 23 noticed packages. The Rust test
itself was not run locally before this commit and is being run now.

Not a price, catalog or picker change; no product behaviour moves.
