fix zsh completion recursion when prog_name matches a builtin helper

The generated zsh autoload entry was named `_<prog>`, which shadows zsh's
builtin `_files` / `_directories` / `_arguments` / ... helpers when
`<prog>` happens to match one. `_arguments`'s `:file:_files` action then
recurses back into our own function instead of the real builtin — on
macOS this surfaces as a "recursion limit exceeded" message that gets
scraped as a phantom completion (test silently passed); on aarch64 Linux
under Nix the pty closes and pexpect sees EOF (issue #821).

Namespace the autoloaded function and install path as `_cyclopts_<prog>`
so internal helper calls always resolve to the real zsh builtins.

Tighten `test_collection_option_repeats` to assert that `first.txt`
appears in the completion list — the previous `assert completions` was
satisfied by the recursion-error text and masked the bug.

Fixes #821.
