The `forceZsh` option on Linux/macOS would use a hardcoded zshPath
without checking if zsh actually exists on the system. This caused
hook commands to fail silently with exit code 127 on systems without
zsh installed.
Changes:
- Always verify zsh exists via findZshPath() before using it
- Fall back to bash -lc if zsh not found (preserves login shell PATH)
- Fall through to spawn with shell:true if neither found
The bash fallback ensures user PATH from .profile/.bashrc is available,
which is important for hooks that depend on custom tool locations.
Tested with opencode v1.1.3 - PreToolUse hooks now execute correctly
on systems without zsh.
