Automate spellcheck configuration based on tool presence

[arran4]

Replaced the interactive promptBool for spellcheck in .chezmoi.toml.tmpl with an automated check. The configuration now uses lookPath to detect the presence of hunspell, aspell, or ispell executables, automatically enabling the spellcheck flag if any are found. This streamlines the initialization process by reducing manual prompts.

Code Review

This pull request automates the detection of spellcheck tools in the .chezmoi.toml.tmpl configuration. Feedback suggests retaining the promptBool to allow users to manually opt out while using the automated detection as a default value, and provides a more concise way to write the detection logic.

[gemini-code-assist]

Automating the detection of spellcheck tools is a good improvement, but removing the promptBool prevents users from opting out if they have the tools installed but prefer not to enable the feature (e.g., for performance reasons). It is recommended to use the automated detection as the default value for the prompt. This maintains consistency with other configuration options in this file (like headless and gpgconfigured) and preserves user flexibility. The logic can also be simplified by applying not | not once to the result of the or expression.

{{- $spellcheckGuess := or (lookPath "hunspell") (lookPath "aspell") (lookPath "ispell") | not | not -}}
{{- $spellcheck := promptBool "spellcheck" $spellcheckGuess -}}
