fix(textobj): use correct config variable, raise log level

Problem: motion keymaps (]], [[, ]t, [t) were never set because
`config.get().debug` referenced an undefined `config` variable,
crashing _setup_buf_mappings before the motion loop. Debug logging
also used vim.log.levels.DEBUG which is filtered by default.

Solution: replace `config` with `cfg` (already in scope) and raise
both debug notify calls from DEBUG to INFO.
