Subject: [PATCH] fix: add command -v happy guard to claude() default-mode
 branch

The claude() function calls `happy` in its default-mode branch without
checking whether the binary exists. If `happy` is not installed the
user sees a raw 'command not found: happy' error with no guidance.

Apply the same guard pattern already used in c() and claude-review()
in misc.zsh: check for either `happy` or the external `claude` binary
via `whence -p`, and emit the standard install hint on failure.
