#10436 b7cfc364aca36bc90f8efa86773bc81011502036 Thanks @shadcn! - Ensure init only runs template post-init hooks for newly created projects.
#10179 d00605c5fb5fe3cfbcb68cea65398430cdd819f8 Thanks @EthanThatOneKid! - Send Accept: application/vnd.shadcn.v1+json, application/json;q=0.9 and User-Agent: shadcn on registry fetches so servers using HTTP content negotiation can reliably serve JSON to the CLI. Fixes #10164.
