Get mac nest working: clean zsh, add bun/rust/claude-code/codex

[tylerthecoder]

Summary

The mac nest was broken — fresh zsh -i printed errors (missing ~/.shenv, missing oh-my-zsh, hardcoded /Users/tylertracy/... paths, kubectl completion failing on a machine without kubectl). The owl binary was being linked from target/debug instead of using the owl setup, which also meant omni-menu was never linked. This PR cleans all of that up and adds the requested tooling.

Mac nest

• nests/mac/setup.json: depend on owl instead of manually linking target/debug/owl (gets release build + omni-menu); add bun, rust, claude-code, codex; add common:claude.sh rc.
• nests/mac/.shenv: trim to mac-specific bits — OWL_PATH=$HOME/owl, EDITOR=nvim, conditional Homebrew shellenv. XDG vars / ~/.local/bin PATH / rc-loop are now handled by owl-start.sh. Fixed hardcoded /Users/tylertracy/... paths.

zsh-ohmy

• .zshrc: source ~/owl/owl-start.sh instead of bare ~/.shenv; conditional kubectl completion; drop hardcoded user paths and Rancher Desktop block; remove git-trim from plugins (it's a CLI tool, not an oh-my-zsh plugin).
• New install.sh: installs oh-my-zsh + zsh-autosuggestions + zsh-syntax-highlighting. Uses KEEP_ZSHRC=yes so the upstream installer doesn't clobber the owl-managed ~/.zshrc symlink (it does by default).

Cross-platform install fixes

• setups/nvim/install.sh: was Linux-only and would overwrite ~/.local/bin/nvim with a Linux AppImage on macOS. Now branches on uname -s, prefers Homebrew on Darwin, falls back to the official macOS tarball, and skips when nvim is already installed.
• setups/rust/install.sh: add Darwin branch using the official rustup curl installer.
• setups/owl/install.sh: skip when owl is already at ~/.local/bin or /usr/local/bin; install to ~/.local/bin (no sudo) on first install instead of /usr/local/bin. The previous check only looked at command -v owl, which fails inside the install script's bash subshell because ~/.local/bin isn't on PATH there.
• setups/claude-code/install.sh + new setups/codex/install.sh: source ../bun/bun-rc.sh so bun is on PATH inside the install script. run_script spawns a fresh bash without rc files loaded, so bun install -g would fail with command not found even though bun was installed by a prior step in the same nest install run.

New codex setup

• setups/codex/: depends on bun, runs bun install -g @openai/codex.

Test plan

• zsh -i -c 'exit' returns 0 with no stderr noise (was printing 3 errors before).
• In a fresh zsh: owl, claude, codex, bun, cargo, nvim all resolve via command -v.
• owl setups-validate — mac validates clean.
• owl nest install runs claude-code and codex installs successfully (previously failed with bun: command not found).
• omni-menu build (deferred — needs brew install pkgconf gtk4 then cargo build --release).
• Other nests not touched, but setups-validate shows the same pre-existing failures (missing secrets setup) on framework-arch / dell-xps-desktop / framework-sway as before — not introduced by this PR.

Note

Medium Risk
Moderate risk due to changes in shell initialization and installer scripts (zsh/oh-my-zsh, PATH handling) that can affect developer environments; changes are localized to setup/CI automation and are largely guarded/conditional.

Overview
Fixes the mac nest bootstrap by simplifying nests/mac/.shenv, removing hardcoded user paths, and updating nests/mac/setup.json to depend on the released owl setup while adding new dependencies (bun, rust, claude-code, codex) and an extra rc script.

Hardens and expands install automation: setups/nvim/install.sh is now OS-aware (Linux AppImage vs macOS brew/tarball) and skips if already installed; setups/rust/install.sh adds macOS rustup support; setups/owl/install.sh installs to ~/.local/bin without sudo and improves “already installed” detection; setups/claude-code/install.sh ensures bun is on PATH and a new setups/codex setup installs Codex CLI via bun.

Cleans zsh integration by sourcing owl-start.sh, making kubectl/bun completions conditional, and adding an oh-my-zsh installer plus plugin installation via a new setups/zsh-ohmy/install.sh. CI release upload now only runs on push (not PRs).

Bun completions path doesn't match install location

Low Severity

The bun completions path $HOME/.bun/_bun doesn't match the actual bun install location. bun-rc.sh sets BUN_INSTALL to ${HOME}/.local/share/bun, meaning the completions file lives at $HOME/.local/share/bun/_bun, not $HOME/.bun/_bun. The [ -s ... ] guard silently prevents errors, but bun shell completions will never load.
