fix: prevent unicode escaping in settings.local.json

Go's json.Marshal escapes `>` as `\u003e` by default (HTML escaping).
Use json.Encoder.SetEscapeHTML(false) to preserve literal characters
in hook commands like `2>/dev/null`.

Fixes hook creation bug where Claude Code rejected the settings file
due to unicode-escaped characters in command strings.
