   Adds zsh completion support using the compdef system for:

   • bitcoin-cli with RPC command completion and context-sensitive arguments
   • bitcoin-tx with option/command completion and file path handling
   • bitcoind with configuration option completion

   These complement the existing bash completion scripts and provide the same functionality for zsh users.

   This PR adds zsh completion scripts for Bitcoin Core tools, converting the existing bash completions to work with zsh’s compdef system. This Improves user experience for zsh users by addressing the need for tab completion support for zsh which doesn’t rely on the existing bash completion scripts.

   The implementation maintains the same functionality as the bash versions while using zsh-native completion functions.

   I’m happy to address any concerns or make requested changes.
