Switch fzf shell integration to modern fzf --zsh approach

[Copilot]

The installer was calling the legacy Homebrew-specific $(brew --prefix)/opt/fzf/install script for shell integration, which no longer exists in modern fzf installs and is the wrong approach regardless of platform.

Changes

• scripts/components/shell.sh — setup_fzf() no longer runs the legacy install script. It now checks whether the fzf binary is present and logs the result. fzf is already installed via the package manager step (packages/common.txt); shell integration is owned by .zshrc.

• files/.zshrc — Replaces plug "zap-zsh/fzf" (fragile plugin that probes a list of hardcoded static paths) with the canonical one-liner from the official fzf docs:

# Set up fzf key bindings and fuzzy completion
command -v fzf &> /dev/null && source <(fzf --zsh)

This works across all package managers (brew, apt, pacman, dnf), always uses the scripts bundled with the installed fzf version (≥ 0.48.0), and gracefully no-ops when fzf is absent. The stale commented-out ~/.fzf.zsh sourcing line is also removed.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• junegunn.github.io
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
