contrib: add initial zsh completion for bitcoin-cli #34364

   Bitcoin Core currently provides shell completion scripts for bash and fish in contrib/completions/, but zsh (which is the default shell on macOS and widely used by developers) does not have any native completion support for Bitcoin Core command-line tools.

   This means users of zsh do not get tab-completion for bitcoin-cli, making it harder to discover commands and increasing the chance of typing mistakes.

   This was reported in Issue #33404: “Add zsh completion scripts for Bitcoin Core command-line tools”

   What was needed

   A native zsh completion script (not bash-compat mode)

   Located in contrib/completions/zsh/

   A minimal, correct starting point that can be extended incrementally

   What this PR does

   Adds a new directory: contrib/completions/zsh/

   Adds an initial zsh completion script: contrib/completions/zsh/_bitcoin-cli

   Provides:

   Subcommand completion for common bitcoin-cli commands

   Basic argument and file-path completion

   The implementation is intentionally conservative and minimal, and can be extended in follow-up PRs to reach feature parity with the bash completion.

   Why this approach

   Keeps the change small, reviewable, and safe

   Avoids large auto-generated or brittle completion logic

   Establishes the correct structure and location for future zsh completions

   Fixes #33404

   Instead of dropping purely LLM generated ai slop to duplicate an existing pull request, it would be more useful to just review the existing pull request and provide meaningful feedback.

   Thanks for the feedback — and sorry about that.

   I didn’t realize there was already an active PR covering this work, and I should have looked more carefully before opening a separate one. That’s my mistake.

   I’ll review the existing PR and provide concrete, technical feedback there.

   Thanks for pointing this out.

   I didn’t know that LLM based pictures are prohibited here, I used that pic just to explain everything in simple form
