chore: add iterm2, bun, and agent tooling tweaks

[akornmeier]

Summary

• Brewfile: add bun and iterm2; pin claude-code@latest
• gitignore: add common dev ignores (node_modules/, dist/, .env*, *.log)
• package.json: bump pnpm to 10.33.0
• tmux aliases: add --verbose to cldyo
• zshrc: fix zsh-completions fpath via brew --prefix

Test plan

• dot update succeeds
• brew bundle check passes after install
• New shell loads completions without errors
• cldyo alias launches with verbose output

Pull request overview

This PR updates the dotfiles/tooling setup to add new Homebrew packages, adjust shell completion initialization, expand global gitignore patterns, and align CI’s pnpm setup with the packageManager field.

Changes:

• Add bun and iterm2 to the Brewfile and adjust the Claude Code cask entry.
• Update global gitignore entries for common Node/dev artifacts.
• Bump pnpm in package.json and remove hardcoded pnpm versions from GitHub Actions workflows.

The previous compinit initialization is still present as commented-out code. Since the new logic is directly below, consider deleting these commented lines to reduce noise and avoid ambiguity about the intended initialization sequence.

This change removes previously ignored patterns (e.g. editor backup *~, swap *.swp, and .netlify). That will cause these files to start showing up in git status across all repos using this global ignore. If the intent is to “expand” ignores, consider re-adding the removed entries alongside the new ones.

compinit is now only executed when brew is available, which means the completion system won’t be initialized on machines/shells without Homebrew even though the rest of the config still loads */completion.zsh files. Also, calling compinit without -i diverges from existing usage in this repo (e.g. git/completion.zsh) and can re-introduce insecure-dir warnings that prevent completions from loading. Consider running autoload -Uz compinit && compinit -i unconditionally (or gated on autoload/compinit availability), and only prepend the Homebrew zsh-completions path when the directory exists.

These commented-out lines look like dead code from the previous FPATH approach. Keeping the old implementation commented in the main rc file makes it harder to maintain and can be confusing later; consider removing it entirely (or converting it into a short explanatory comment about why brew --prefix is used instead).
