fix: handle both boolean and string types for settings

JSON.parse preserves native types, so boolean true/false stay as
booleans rather than strings. The previous check only handled string
'true', meaning users who set `"ENABLED": true` (boolean) wouldn't
have the feature work.

Now both `getBool()` helper and ResponseProcessor check handle:
- String 'true' → enabled
- Boolean true → enabled
- Any other value → disabled

Tested: Confirmed feature stays disabled with string "false" and
no new CLAUDE.md files are created when accessing directories.
